Well, speaking for myself, not sure if "faith" is the word I would use for myself...however I feel good he will have a really good chance to be ready earlier/faster than some other players recovering from similar injuries like his. Reason being the Bills facility is one of the very best, if not the best in the league. It is said by many to be the best thing ever.
With that along with the amount of hard work, determination, etc Tre is putting in to being ready just gives me confidence he will be ready faster than some may think.
