"Catchability"?

[Lintner5]

From what I've seen & heard about when it is/isn't appropriate to call pass interference, if the pass is thrown in the general direction of the contact (e.g., left, middle, right) it is pass interference even if the pass is substantially under-/over-thrown. However, if contact is on a WR doing a fly pattern near L's sideline & the pass is thrown to the flat on LJ's side, pass interference isn't appropriate.

On an overthrown pass, it's hard to say. If the pass is beyond the receiver when the contact occurs (but the ball hasn't hit the ground yet), it usually doesn't warrant a call. However, if an overthrown pass is obviously not going to be caught (e.g., a line-drive pass but 3 yards above everyone or a pop-fly pass with a trajectory to go well beyond) but the contact occurs before the ball clearly passes the receiver, this usually warrants a flag.

Also, know that in these situations, you'll hear from one sideline or the other because both all pass interference calls & the judgment involved usually elicit more chatter and because our rules differ from the NFL & NCAA in determining catchability.
