one of the fundamental differences i see with Babers' bubble screens is that the QB is trying to throw them as quickly as a person can humanly throw them. It's almost one motion.
Most bubble screens and particularly Mcfukits, were really slow developing and telegraphed. It taook so long for the ball to get out there an old lady in a walker can blow the play up.
Some of Babers' bubble screens will get blown up and that's ok. They're hoping to get 3/4 yards a clip, like a run (as Mcfukit preached) but they're also designed to keep the defenses honest and spread out. Get the ball out quick, and thrown correctly to the right spot, block them and they'll get 3/4 yards consistently. Some they'll break, some will get blown up.
would be interesting to chart a few of their games, and put percentages to the bubble screen success/failure rate and number of times run.
