1. Con: Sometimes you need the outlet right off the bat. And the keeper gets rid of the ball in 7 seconds anyway. It isn't always abused, so why kill the legitimate use.
2. No real Con
3. If done the same way as pbox timer, you'd get some random resets that just wouldn't be fun. If not done that way... then explain the problem with the bomb-ball mutator. Also, if a player can only hold the ball for so long, the defense doesn't have to guard someone who gets the ball far back, and can just do heavy coverage on everyone else. With any reasonable timer, the player wouldn't be able to walk the field... and through heavy coverage, couldn't get a good pass off. If he can get all the way down the field, then the timer is useless in the first place.
Last bit of comments jsut to beat a dead horse.

If you're going to know the shotclock example.. be familiar with the history.
-Full court press didn't prevent ball holding techniques. A matchup of th best teams ended in a 3-1 4th quarter.
-Ball control was, and still is a major part of basketball. Its just that now ball control is limited to 24 second intervals, where you can't hold it more than that without giving a reasonable chance to the other team.
-In Deathball, unlike Basketball, you CAN foul someone and get the ball without penalty. The skill lies in being able to foul them in the correct intervals, because health regenerates (not a bad thing).
-I have made no valid point, and my argument does not have any force in either direction.
