i applaud the aggressive, progressive approach of this thread to improve the entertainment value of the game. Dealing with 3's is a good start but, unfortunately:
1. reducing the 3pt line to the back-court area would have the opposite effect because defenses could cover it more effectively.
2. we need the 3 late in games to keep the losing team in it. In fact, i'd add a 4pt shot from half-court so there's a remote chance before the buzzer sounds. A way of limiting 3's might be good, but not in the 4th.
the greatest thing about a football game is the variety of ways an opponent can come-back in the end
