In fairness, I think a lot of the QBs the Browns have taken in the first round were not going to develop regardless of who drafted them. Manziel, Brady Quinn and Brandon Weedon were desperation/reach picks.
Given how he is playing with the Bucs, the Browns definitely seemed to **** the bed in their handling of Mayfield, and I thought Tim Couch was better than he was given credit for, as he could have been something in a different situation I believe.
Couch had some good games against the Steelers, but generally took a beating with the Browns and injuries prevented him from catching on anywhere else.
Mayfield's performance with the Bucs seems to give Steelers fans hope for Fields with the Steelers, due to the Bears generally being as much a QB graveyard as the Browns have been, but despite Mayfield's struggles with the Browns, he showed a lot more with them than Fields did with the Bears.
Honestly, Fields has looked better than I expected him to through two games, but the consistency and point production as yet to be there, as he averaged a lofty 2 yards per pass during the second half in Denver.
