I would probably add Eli Rogers over those other two guys. He was wowing people in camp last year before he got hurt during the pre-season, and he may even wrestle a return job away.

I actually haven't heard a lot about Rogers other than he's the WR3, which is a pretty nice role to have on that team. There was more news about Coates doing well in camp, and then more news about Coates not doing well in camp, than I seemed to see about Rogers. I'm not sure he's a longer term answer but with TE up in the air for Pit he has a chance to be a factor early and then who knows from there...

For what it's worth we have Rogers rated the highest for this year. I think either of the other two guys may be a little better of a prospect but at this point I think you're better off adding Rogers just to see what he does in the short term in a pretty nice role. It would also depend what else you have at the position and just how deep Rogers would be on your depth chart. Seems worth it to me.
