Since Bills negated the FB position in practical terms , Daboll was asking Knox to motion to the backfield for blocking quite a bit early on.
If he becomes a better Lee Smith who can also run a seam route ? Bills should build on that. and continue to upgrade with focus on making the position a strength for Allen to make use of since Josh has finally learned to check down when the primary play call is covered
But we certainly do not have the answer as a pass catching TE on the team yet.
I can still hope he can reach a higher ceiling with his receiving skills , and soon !
