Every quarterback has a nightmare game like that at some point. The greatest QB of all time, Otto Graham, once had a game where he went 2-for-15, 31 yards, 0 TD, 3 INT. You burn the tape, flush it and get back to work. The best way to put it behind you is to go out and throw for 300 yards and 4 TD's in your next game.
That first pass was high risk-low reward because if it WASN'T picked off there were STILL 2 Pitt defenders in position to plant the intended Syracuse receiver into the turf well short of moving the chains. This pass should have only been attempted if Syracuse were already deep in Pitt territory or on 4th down with less than 2 minutes left in the half or the game.
