I don't know that the jailbreak goal rule would really make a big difference but it'd be cool to see the sport continue to evolve and adapt. Definitely agree the 3-2-1 points system is preferable, though I doubt it ever happens.
I'm also so f***ing sick and tired of shootouts that I'd go 10 minutes of 3-on-3 with maybe a full 2 min commercial break at 5 minutes or something because guys would bitch about being winded. Shootouts are traaaaaaash, dude. I turn the game off if it goes to shootout 100% of the time, regardless of who is playing.
