I'm not saying he would be making the same plays in Miami's defense, as a nickle corner he was just average. Miami's secondary, with all the injuries, has been any worse without Fitzpatrick. I realize he was he was ess than 20 games into his career, but in Miami's scheme he wasn't worth a 1st round pick.
I think they wanted him more in a LB/rover type role on this current defense. As you saw today, Cleveland had most of their success on those quick slants, especially inside, and a guy like Minkah who can see whats in front of him closer to the LOS and diagnose would be beneficial to coach Flo and PG while trying to develop his young, inexperienced squad.
This is a guy who bragged on his ability to be placed anywhere a team needs him . . . so much for that.
That doesn't mean it would of stayed that way or that he wouldn't excel there . . . we will never know, because like others have commented as soon as he faced some adversity he cried his way off the team and his momma cried for him on Twitter.
Nobody wants that in the end.
