Let revisit a couple plays before...

All the QB can do is throw the ball, whatever happens after that is not up to him and the players that make or miss the play have nothing to do with him or his performance.
Bad throws are bad throws and good throws are good ones. You judge the QB on what happened on the other side, I would judge them by whether they made the right decision and put it in the right spot in clutch time.
On the Tyree catch Eli made a great escape and put the ball in a spot the WR could catch it - It was an excellent play on his part. The play before the DB had an int on a terrible throw that should have lost the game for the Giants but as fate would have it Samuel dropped the ball.
