100%? Of course not. But take any great or good QB in that situation.
This moment in particular: 4th quarter, down by 2, red zone, 2nd down. Force a pass to a well covered Decker... INT. On second down! Then proceeds to throw two more INTs after that. Choked.
Not to mention doing crap before that for most of the game. Say what you will about Rex, but he is a great defensive coach. He knows how to shut down Fitz's limited ability.
To be fair to Fitz though, there were 21mph winds that day. That's pretty challenging to a guy who throws 25mph.
Would Brady have pulled out that win? Russell Wilson? Sanchez? Hell even Geno? I'd say yes to all of the above.
Fitz is a great guy. Smart (to a point) and can come in when needed with an understanding of the offense. But even with being "Harvard" smart and knowing a playbook, he still lacks the ability to survey the field. One or two reads tops.
He can get some Ws vs lower to midrange teams when needed, but will never get you over the hump. No matter how much talent you surround him with.
(Disclaimer: If the Jets go against my opinion and sign Fitz for stupid money (7mil+), I reserve the right to deny any attachment to these anti-Fitz comments. My account was hacked by either @Joker or @Tunescribe.)
