NBA
1.) Get rid of advancing the ball on a timeout. It makes a late shot, but non-buzzer beater, meh, because the other team is going to get a solid response.
This is the dumbest rule in all of sports. The most exciting play in basketball is the long pass and shot and/or mad dash up the court w/ a few sec on the clock and it doesn't exist in the NBA.
less timeouts pleassssseeeeee. or at least say only 2 TOs a quarter so the final minutes aren't so damn long.
NCAA Football
-you sign w/ a school you get 4 years tuition there.
-I could expand on this. A real way to help student-athletes or athlete-students and keep them as "amateurs" and not seem like greedy scumbags. For every year you stay at a school you get 1 extra semester of paid tuition for playing in D1 after no more eligilibity. This is a real benefit. Grad rates would skyrocket because you'll be 22-23 and have to take education more seriously after your NFL dream is crushed (not to mention its easier to study when you aren't getting your skull bashed in). And if you a good student, you get a masters. If you transfer you lose this benefit. The money is there to do this for all scholarships and if its not, tough, go play FCS.
NHL
-widen the rink, players are so much bigger than they were in the 70-80s
-2 min pen for spread eagling yourself on the ice to block a shot
-goalie pads could be curved, you know like legs are designed
NFL
-put sponsors on the jerseys, heck let unis look like NASCAR drivers, I don't care. anything to have less commericals. the AAF was more watchable for that reason alone.
