Taylor was never a legitimate starter in Buffalo.
And really the only ones that can make sense of their draft board and if a jump is needed are the Bills. All depends on who they value the most. If they want Rosen and on their board he's far and away the best...yes trade up. If they have someone like Mayfield high they can see how the draft plays out and make a smaller jump possibly. If they have Lamar Jackson high they can sit at 12 and likely get him while keeping all their picks.
Whatever they decide to do one thing is certain. More people than not on here will complain and say it was a stupid move while half hoping the guy selected fails so they can keep crying out how they are so smart.
Point blank, period.
