MMMMMMMULTIBALLLLLLL

Any sport, doesn't really matter. Periodically during the game more balls start getting added into the playing field to spice things up, a la pinball tables.

Tennis, Football, Volleyball, Baseball, Basketball etc etc

All sports: ban gambling sponsorships. Ban teams from wearing gambling company logos or otherwise promoting gambling companies. Ban leagues and networks from incorporating gambling sponsorships into the programming.

I would also say ban gambling advertising entirely, but that's a government law, not a sports one. With the sports rule change, gambling companies could still buy ad spots during as breaks. Just no commentators going "and now over to Lad Brokes so the punters can know the odds in this game".

As someone who is forced to watch baseball by their fanatical wife: the MLB should adopt most of the rules that the Savannah Bananas use, including a fan catching a foul ball counts as an out, trick plays, inning timer, etc.

For any pro sport known for rowdy, destructive fans - the clubs get to pay for the police and insurance expenses.

Oh, this would bankrupt the clubs, I hear you say? Oh no. Anyway...!

Soccer: yellow card for faking injuries (you can easily see players close to death that jumps us and run if no whistle is blown) and for protesting with the referee. Also, microphoned referee so that the whole audience can hear what they say (it will result in LOTS of red cards until respect is shown)

Basketball: intentional foul is two free throws and ball, three in the last 2 minutes

Football: proper helmets

Yellow card for faking an injury in soocer

American Football: no time outs.

Play it just like soccer. Ref's calls are final, and the clock doesn't stop unless their is an injury.

It would make the game much more fun to watch, cut the runtime by two thirds, and force teams to hire athletes who can maintain vigorous activity for half an hour without dying.

I would add that at any given time during a football game a fan can throw a new football on the field and two balls may be in-play at that time.

why?

American football:

Universal:

1. No TV timeouts. The game is already insanely stop-start. Get your shit together, TV broadcasters, and make it work as-is.
2. No "wounded duck" pass interference penalties on poorly thrown balls. Defenders in pass coverage should be entitled to their existing vector of motion.
3. Players leaving for injury must be out for 4 plays or more, maybe the length of the existing drive. Something though. One play is not sufficient to dissuade simulation for tactical advantage.

Stuff to try in college or the spring league:

1. No radio communication. American football can be too regimented sometimes, and old men treating young men like chess pieces is part of that.
2. Limited substitutions per play if there is no is no change in phase. You come out, fine, but you're not going back in until the next time your team is on offense/defense/special teams. This will also enhance numbers 1 and 3.
3. Even shorter play clock. Keep it moving. Adjust when the clock runs if you want to keep the number of snaps consistent.
4. Remove kicking entirely. They're vestigial minigames at this point that could be replaced with throwing the ball. Workshop it in the offseason to see how small the goalposts need to be to replicate current play balance.
5. College only: Admit they're professionals, make them employees with enforceable (and purchasable) contracts, and route enough money into the non-revenue sports to keep them viable. It is what it is; don't let the creeping in of sensible labor practices destroy the sport. Use the inevitable anti-trust exemption you'll get to mandate some sort of nexus between the players and the schools (lifetime tuition waiver? part-time enrollment?), but stop acting like the already snobbish and laughable "amateurism" of the NCAA is even a viable concept.

Stuff to bring in that would make the game weird to modern eyes but might help reduce head injuries:

1. Mandate wide splits on the lines, two-point stances, and a wider neutral zone so that players are not exploding into each other head-to-head. A snap should look like a sumo match, not two horny rams on a hillside.
2. To allow for number 1, make "1 yard to go" the minimum for a given offensive snap.
3. Remove most/all of kicking again, though with the idea of reducing high combined-velocity impacts rather than just because it's anachronistic. Treat an incomplete pass on fourth down like it was a punt. Give up on the idea of kickoff returns. Field goals could stay, but subject to the same scrimmage rules as other plays.
4. Consider whether every play from scrimmage should require the Offensive Line's first step should be backwards or lateral. They already are on many passing plays, but making it mandatory would further encourage upright play that's often ineffective technique today. The running game will be severely affected, but it is what it is and "every run play looks like a draw play" is a small price if we want to save American football over the long term.
5. Revamp tackling rules. Make it rugby style and penalize hits above the shoulder harshly. Consider whether big hits resulting in heads thumping against turf are common enough to be banned altogether.
6. Consider removing helmets so players have a sense of preservation over their own heads, but if not that, then go with something much lighter and more ice-hockey style so the helmet is not as tempting as a weapon and doesn't encourage a false sense of invulnerability. It was for all the wrong reasons, but the "Extreme Football League" (nee "Lingerie Football League") uses this type of headgear.

American football

I would remove defensive pass interference from the game. It’s been abused by offenses, they just throw it up to the guy way down field and if anyone touches him, first down there.

I would also get rid of the QB slide rule so many abuse for extra yards. You have the ball? You can get hit.

Baseball. No sponsorships on uniforms.

I guess we could extend that to most sports. I know soccer is much more lax in that regard.

All professional teams that are televised must be broadcast free of charge to their local area. No local blackout restrictions. (Fuck you, Marquee Sports. Put the Cubs back on WGN.)

Beer must be under $10, in stadiums. It's $16 for even shitty domestic beer at Wrigley. It's damn robbery.

All sports have an alternative league where performance enhancing drugs are mandatory to participate. That's way more fun.

I'd completely remove the icing rule from hockey. I don't really understand the point of stopping the game just because the puck went back to the other side of the rink. It's not like it stops the defending team from dumping the puck out and purposely starting a face off.

College football: when you win the coin toss, you have 2 choices: kick or receive. No more deferrals.

Cricket:

1. Remove the backfoot no ball. It does not benefit the sport but puts a lot of stress on bowlers bodies, knees in particular. The most commonly injured body part for bowlers. They land with 6x the impact of their bodyweight on one knee 6 times an over, like 20 overs a day. No good.

2. So much I would change in Odis that i dont even have the energy to wrote it all.

3. A shit ton of administrative changes.

4. Mankads to no longer be stigmatised (they are legal already)

5. Allow some level of ball tampering, by which I mean not using anything but allowing some controlled substances.

6. Add substitutions

Something I'd like to see on every hard cap league is a cap relief calculation for team drafted players, going up the later that player was drafted. Maybe 5% per found, maybe 7.5%?

So many times teams are basically forced to move on from role players that are fan favorites because it's literally impossible to pay a team of veterans under the cap unless you have no star players and I think it would be genuinely interesting to provide a benefit on the cap side to keeping drafted players in house past their first or second deals. Part of why it's so hard to be a fan is knowing that anyone but the absolute TOP stars are just consistently going to be moving on in a few seasons.
