That, and a competent coach who can actually get something out of the unit.
For 2008, we've talked a lot about life after Marvin Harrison mainly because 2007 was the first time Marvin ever sustained a serious injury. Even though both Jim Irsay and Bill Polian have stated emphatically that Marvin will return 100% in 2008, most of us think that the Colts must look for another WR to round out the group. We've talked about guys like Arman Shields and Harry Douglas, but lost in the shuffle is Hall.
Hall missed most of 2007 with an injury. His training camp performance was mixed and his pre-season results were dismissal. However, as he has healed up from 2007, Hall has worked hard to develop himself as a receiver. In a recent video interview at Colts.com, Hall (who is attending voluntary workouts) said he went to a WR clinic recently to work on his fundamentals: Hand-eye coordination, route running, blocking, etc.
While Hall is a bit of a project, he seems to have the mindset to develop. Rookie WRs are usually garbage. WRs in general take a few years to season. Reggie Wayne was awful his first two years before developing into an elite receiver. Anthony Gonzalez, who was a top rookie WR last season, struggled early on. So, it is posible that Hall could provide the Colts with what they need (WR depth) if he develops his skills going into years two.
