I think that Worley will have a solid year, but the magnitude will depend on the O-Line. IIRC, Worley was a Gatorade Player of the Year, which is not a small achievement and not just handed out for any QB.
From a personal basis, Worleys' largest challenge may be overcoming the lack of talent development from Dooley's tenure. This can be said of many of the recruits from that window.
Chaney is a good OC.
