It has become obvious that Gardner has mad skills as a receiver, and is only going to get better, as he gets used to running routes and has more practice with Denard.
It would be interesting to see what would happen if Gardner has an outstanding season as a receiver. He already has a good start. Would or could Devin be offered roster number "1" next year? More than that, would Devin even consider accepting "1," because that implies a tacit acceptance of a permanent move to WR.
Gardner has made clear that he is a quarterback first and foremost, and that he is receiving this year in order to help the team, and in order to get on the field now. All well and good. But based on the current season, and also the next Spring Practice (and how he does at QB at that time as compared to Bellomy,) I could envision Gardner being "strongly encouraged" to continue as receiver in 2013.
Obviously, this is all premature speculation. Which is what the internet does so well.
