I watched him about 5 plays very closely vs. detroit. I'd say, maybe by mid-season he'll be an ok 10-15 play sub. Right now, 5 or 8 p/g I'd say. Because Willaims must rest and Troup must learn. I think, what you want to see is explosion and power or athleticism (like big teddy w), troup held his own, kinda, but did not look special in any particular way... imho...
good effort and hustle though...
GO BILLS!
