‘If the Bills think Rosen’s the best, it will cost them plenty to have a shot at picking him. They would likely have to trade all the way up to the Giants’ No. 2 pick, and the Giants could probably name their price. At the very least, it would be Buffalo’s two first-round picks and a second-rounder this year, maybe both second-rounders. Or, it might be both firsts this year and the Bills’ first-rounder in 2019.’
