Of the 32 teams how many are going into a season with a starter who missed 6 games in his rookie season due to injury? The backup plan leaves something to be desired. Fingers are crossed.
why would that be a worry for a Bills fan?
I don't think he failed miserably. He showed flashes, but, missing 6 games is the (negative) key for my concern.
So, we'll put you down in the "Thaddeus Lewis was the best backup option available" camp.
