Pat had good games against the Spurs and the Pelis last year as well. It is clear that he is a useful NBA player.
Layman never had this (out of garbage time) yet, but we have not seen this from Pat until his 2nd year in the league - Layman is just now entering his 2nd year.
I suspect that like Pat, he will become a rotation player at some point. He has too smooth of a handle, athletic ability and shooting form not to. I would suspect he might become a better player than either Crabbe and Patty actually - simply by the way he moves on the court - but I believe that both these guys are good NBA caliber bench role players, maybe more if they put the work and fall in the right place.
