I'm not that worried about Fitzpatrick winning too many games. He had a much better supporting cast in Tampa, eventually got benched, and Tampa is still picking 5th overall despite that brief run of good play that he had. He's also a year older and will be playing behind a line that is Tunsil and pray for rain.
Bottom line is that I believe the reports that Ross really, really wants to take a run at Tua. Grier won't get fired if Fitzpatrick turns out better than expected and the consolation prize is Fromm or Herbert, but he absolutely will get fired very soon if they draft a QB this year and it's not immediately apparent that he's going to be a star.
Do you have a link to this? I haven't seen it, and it would be very interesting.
