Cleveland has so many picks, they can select Mayfield or others and still set themselves up for another QB pick in 2019 by trading down with one of their 2 top 5 picks.
I'm not going to claim expertise on this but I've been listening to serious and no GM is head over heels on any of these guys. And these are GMs who aren't in line to take a QB.
It's amazing how everyone just falls in line with the top picks...yet year after year, picks past the top 10 end up being the best.
BTW, Bills GM said nobody has stacked their board at this time and no one has decided on anyone since they have not gone through workouts and interviews. He said until the interviews are done, absolutely nothing is decided.
