Looking at how NE use Welker in the slot and how he uses his speed to get open and accumulate a lot of YAC, what would be the downside of the Steelers keeping Wallace as the #1 WR, but lining him up in the slot? In multiple sets, have Brown and /or Sanders/Ward/Cotch on the other side with Heath as the TE.
Not looking to reinvent the wheel here, but would be a neat little wrinkle moving forward in the season. Think of the matchup issues it would cause putting a speedster like that inside. Now you're forcing a CB inside and a safety to cover the outside WR.
I think it would benefit the Steelers but am curious as to what the rest of you armchair OC's think. . .
