I just didn't see anything that special in his highlight video.
He reminds me of the 6'5" preseason wonder we had in training camp a couple years ago who looked good on deep throws in preseason, had a couple long TDs from Russell, but was a one-trick pony and was useless on special teams. Can't remember the dude's name. He may have made the opening roster one year, then gotten cut.
To my eyes, Jerome Kearse looks like 3X the player this Duron Carter guy is, especially when ST value is factored in.
