This should not happen, ever, in my opinion.

My QB literally just runs around in the backfield and goes back 11 yards eventually and fumbles in the endzone without apparent contact. lol. He should have thrown it out of bounds once he was trapped at the sideline. Or he should have hit the open WR.

This should be fixed with the new pocket updates in 0.4.1 - just pushed the first release candidate to MFN-1, if all looks well there through the rest of the regular season (Monday is week 9) that will most likely be the timetable when the official release will happen.
