I made this argument on a thread from a few weeks ago, but the reason why it didn't make sense for Deejay to play CB or Safety is because the learning curve at those positions is much harder for a True Freshman than it is for WR.
Deejay is talented enough to play DB, but as a TF & even as an EE he wouldn't really play much considering he barely ever played it in High School.
With Deejay, he's got 4.4 - 4.5 speed & is naturally quick, when you watch his HS tape he accelerates like crazy on those runs once he finds a crease. He's the kind of player that you just want him on the field with the ball in his hands, he's big enough to play outside WR or in the slot & you can use him on an end around sweep as well.
If you remember, back at Paradise last year he caught a 70yd deep ball TD & and Richt was so impressed with his WR ability, he called him a "future 1st round pick".
With Ahmmon, Mullins, Cager, Berrios, Deejay & Dayall, then with Njoku, Thomas & Harley all coming in this summer we'll have plenty of quality depth at WR.
