call me a grumpy old man - but he's grabbing the ball with one hand when it isn't necessary/should be grabbing it with 2
I kinda hear what you are saying....damn young whippersnapper show-offs!
But go back and look at the first, he probably has to bring his body further around to get his other hand in position to wrap the ball with both hands in which case very likely he wouldn't have been able to continue upright into the end zone....momentum probably takes him to the ground or puts a great deal of stress on his knees.
In the second, its just dirty, but look at the position of the DB including his head........because Beckham left that other arm down no way for the DB to know when to jump, most DBs are watching the hands go up for timing, the ball is other side of the DB and Beckham otherwise has to go through him to get both hands on it.
Solid reasons for both of those IMO and he really is just that good
