Different perspective for a minute and just my opinion. This change to the game is not a move forward, rather a move backward.
People got creative and used the tools available to them to create a new move--the pinch and pop. Rather than outlaw the move, those people should be thanked for creating something that is exciting and fresh, not too mention extremely successful and cuts down on bone crushing collisions (yes I know, the tough guys out there like the collisions). But as another poster pointed out, the best is only winning 70% of the time at the D-1 level...so lets not give this new move too much actual game impact as the best have always won around 70% of their moves. So the only difference is the amount of collisions and resulting injuries.
Even if the impact on possessions was great, isn't that why colleges try and recruit the best players? Football rule changes are just the opposite--move the PAT back so that the better kickers can get the points...give skill a chance to make the game more competitive for those willing to do the work. Move the line of scrimmage on the kickoff up so we will have less bone crushing hits. Make skill positions more skilled. Imagine if they outlawed the curve ball in baseball because one guy did it better than everyone else??? What if they said David Tyree can't use his helmet to catch the ball???
No, not that simple. This step backward makes the time it takes to F/O far longer and will just result in the two toughest guys on the field fighting each other for the ball. Completely taking away skill and athleticism and creating a fight. That is a step backward I/M/O.
Ball in the back of the stick is withholding ball from play? I guess they haven't seen a guy with the ball running around with the ball in the front? What is the difference? Ball is dislodged from the front or the back quite easily. They put the ball in the back because there is just enough grab to let the person lift the ball from the ground and move away from the other player. Hit that shaft with the ball in the back and I would argue it is in fact easier to dislodge as there is no pocket to protect the ball. Have you seen how easy it is for them to pop the ball out?
The premise that the back of the stick is some how a stronger position to interact with the ball is plainly false. If it were true no one would use the front pocket. So silly an argument, but one that the rules committee knows can easily manipulate those who haven't played the game.
I would prefer to d up against some poor soul with the ball in the back pocket every day of the week (played for many years and I for one like the new move because it adds some excitement to the game). Most of the people liking the rule-never played this game - or are stuck with the memories of how they played the game. It is those people and the rules committee that need to learn to accept the change and help grow the game rather than moving it backward...my opinion, but fire away...
