Oh it's much more mental than physical. Dak's problem is his own lack of patience and that of his OC. They both need to accept that when teams play that cover 2 shell you absolutely HAVE to take the short throws and keep matriculating the ball down the field. He also needs to quit letting defenses trick him into audibling from run to pass based on the fake stacked look. When they stack the line to try and force you to get away from a pass you can't always fall for it. Sometimes you simply need to audible into a run play that takes advantage of the fact that they have so many pieces stacked in the middle. Shift to an overload to one side, seal the edge and run off tackle or outside. Catch them stacking the middle and make them pay for it .. not by audibling to a predictable pass play into dropped 7 or 8 guys but by sometimes running outside. Seal them off and eat them alive off-tackle.
