DeCastro was a rookie last year, who missed nearly all of his rookie season due to an injury suffered in the Bills per-season game. Kind of a strange comparison, IMO.
I don't recall many people lobbying for the Bills to draft Watkins, an overaged rookie, with their 1st round pick.
Better Warmack than an overrated, system QB like Geno Smith, IMO. He has some gaudy numbers, but that's about it.
