The Jets were always behind so it was bound to happen there. I saw him fail miserably last season against the Rams and Steelers. Thats the Geno I know and expect. Again, win a game against a decent team and then we'll talk.
Fail miserably against the Rams?
He came in cold in the 4th quarter, immediately led a 98 yard TD drive on his first possession, led a 46 yard field goal drive in his 2nd possession (scoring more points than we had in the first 3 quarters with a healthy Russell Wilson). Then on the final drive where he had an opportunity to win it, his intended target fell over after the ball was in the air leaving an uncontested catch/interception. Geno did literally everything you could want from a QB in that game to win it - perhaps if he'd played 4 quarters we do.
Likewise against the Steelers, after scoring 17 2nd half points to keep us in the game, he drove us up the field in the 4th quarter, and with 15 seconds left, instead of stepping out of bounds, Metcalf decided to try and tackle the defender, fumbles the ball - almost loses it, and instead of having 3 or 4 attempts to score in the red zone, we have to spike the ball next play to leave us 2 seconds on the clock to kick a FG (which still takes us to OT and a chance to win). Now sure, OT didn't work in our favour and TJ Watt made a great play to force a fumble, none of that sounds like "miserable failure" to me.
It's definitely not Russell Wilson running into a 15 yard sack against the Bears taking a 25 yard chip shot to 40 yards in horrendous weather which was subsequently missed, putting us out of (granted, very slim chances of) playoff contention. THAT'S miserable failure.
