Fitzpatrick's history is that he gets really hot where he can play out of his mind and be super productive and then can cool off and have games where he throws balls that are head scratchers. Last year in Miami he was playing very well and really didn't deserve to be benched when he was with Miami in position for a playoff berth. Does a player become more consistent at age 37 or 38?
A similar question to the one in 2018 when we traded for Alex Smith. In 2017 Smith was one of the top rated quarterbacks in the league and going contrary to his prior history put up very good numbers in yards per pass attempt, completions over 30 yards, etc. But was that really him or him being supported by an uber talented offense in KC?
At least with Fitzpatrick you couldn't say that the Dolphins talent on offense came anywhere near what Smith had in KC and Fitzpatrick did make many plays on his own improvisational ability.
In that regard I think we know better what we are getting in 2021.
One has to think that Rivera with a talented defense is not going to have Fitzpatrick throwing the ball 35 times each week, and will be looking to limited turnovers on offense, etc.
