If we are going to go with a lot of spread formations & RPOs then Mayfield & Jackson would be the best fit. If you want a more conventional pocket QB then Darnold, Rosen or Allen would probably be best. If you want to mix it up then you might want to go with Rudolph or White. It really depends on the type of offense we're going with which is why I feel we're better off keeping our picks and going with a QB like Rudolph.
While I still feel our next biggest need is LB then DT, I am on board with grabbing Simms for the O-line as it would give us some depth with Groy & the possibility of Glenn coming back (Richie is a beast but he's not getting any younger). We need an elite sideline-to-sideline LB to really take this D to the next level IMO.
Let's Go Buffalo!!!!!
