Hard to tell with closed practices; but that's just 1 person's impressions after talking with staff about who's trying to step up and stake a claim to a starting position. That sophomore class had several very similarly sized and talented WR's, and I expect to see Dunbar, Clark, and Patton all get plenty of PT... Patton and Clark will also probably get some return opportunities. I thought it interesting that Dunbar had shown so much in practice that he was listed as a starter, even though he doesn't have any catches in real games yet.
Of course, any of that can change before week 1, depending on who looks best in practices, and that's just 1 unofficial post-spring depth chart. With that many hungry WR's, I'm sure there are a dozen different variations of the depth chart at that position.
