Some of my guys...
Charles Clay - I saw one other person mention him in this thread, but I am quite high on him (at least as a deep stash). On MFL he is still listed as a RB, but I"m hoping he is converted to TE going into next season. He didn't receive a carry this year, but being a FB/TE hybrid always gives him the chance for some cheap one yard TD runs as well. It would be pretty nice to have a short yardage back and tight end combination.
David Gettis - I am a Panthers homer, so maybe I'm a little biased, but he showed me much more in 2010 than any other Carolina Panthers rookie WR in recent years...and that was with Jimmy Clausen throwing to him. I think he'll battle Lafell for the #2 job (I don't predict Carolina signing a big free agent WR like a lot of people do), and even at the #3, he'll get plenty of opportunities.
Joseph Morgan - He made cut after cut with the Saints when he wasn't supposed to, and rather than cutting him and trying to stash him on their practice squad, they placed him on IR after he suffered a minor injury. I don't think the Saints would have done that if they didn't have see something in him. He may be mainly a kick/punt returner going into next season, but I think he has a chance to make an impact. If they are unable to sign Colston and a few others, he could end up being a 3rd or 4th receiving option with upside.
Josh Morgan - I'm surprised to see him on so many waiver wires, but I have been able to pick him up in every league I'm in. I believe someone mentioned him earlier in this thread, but he is a guy that will probably never have a Pro-Bowl season...but I see no reason to think that he shouldn't be a fantasy WR3 when he comes back.
Dennis Pitta - Another guy that I've been able to pick up off the waiver wire in a couple leagues. He and Dickson are probably going to battle it out in Baltimore for the number one TE spot, but he showed quite a bit of ability this season. He is good in the redzone and Roethlisberger seems to own him. As the last TE on my roster, I'm quite happy with him.
Rob Housler - He didn't get a chance to show too much in Arizona this season, but I think he has a legit shot to at least take over Jeff King's spot in Arizona, and start to compete for Todd Heaps role. He'll need to prove his ability to block a little better before he can win a ton of snaps...but in this new age of athletic tight ends, he could be in line for some chances this coming season.
