You may be right, but logically I can't help but think a receiver is going to do whatever he can to either catch the ball, stop the defender from intercepting it or try and draw a PI call. Not much different than a player over reacting on a hit, trying to garner an unnecessary roughing penalty.
Or a defensive lineman flopping. Offensive linemen grabbing fabric at the shoulder pads is permissable by officiating practice so long as the defender is under control. "There's holding on every play". True, but there is permissable holding and the other kind. The flop is intended to create the illusion of a change of direction, a release from control, with the lineman still having that chunk of jersey. It's intended to look like a legit win and hold where the defender has beaten the O-Lineman who holds on for dear life (or more rightly his QB's or running back's).
Getting back to receivers, trying to draw a PI call is divided focus on a catchable ball. If he sees it as not catchable, I suppose he might slow down or angle into the defender hoping the defender runs into him and he gets the call. I'll grant you that much, but if the ball is not catchable he's probably not going to get the call anyway. But if he does it is a product of a bad throw.
Consider the sideline back shoulder throw. The concept is the defender has his back to the throw and won't see where it is going whereas the receiver gets his head around and adjusts to the ball. A good throw is well timed and puts the ball where it is catchable. Equally important is the ball is put where the defender cannot catch it if he happens to sense what's coming and whips his head around. Catching it requires focus on the ball. Now, if it's a poor throw, too far inside, the receiver might have to flip toward the ball and stop short. The defender might run into him with a PI called. Again, it's still the product of a poor throw.
If you get those calls, great, but that's not the object of the play; instead it is a lucky product of a mistake.
If Flaco draws more of these calls than others perhaps it is because of (1) accuracy issues or (2) he just likes to throw a lot of jump balls where the defender has a legit shot at it, chuck and pray, where two out of four possible outcomes are negative, with one of the positives being a possible PI call or (3) every time he thinks he sees a hold he immediatly throws there, which would not always work out. If his guy has a step, and he underthrows on purpose instead of trying to him him in stride, how much sense would that make?
