The Bills don't plan on using him as a blocker, but he can chip and be a receiving target out a variety of formations and line up in different places to help force coverage mismatches.
IMO, if Kincaid is as good as they say he is as a receiver, he will simply box out smaller CBs and safeties and run away from LBs. His basketball skills should help quite a bit in terms of body positioning on those type of plays.
