It's pretty thin, but there are guys there that could be of interest. Frankly, I think Asa Jackson will prove to be more than enough, but for conversation's sake...

Patrick Crayton
Johnnie Lee Higgins
Stefan Logan
Chansi Stuckey
Justin Forsett
Mewelde Moore
Jim Leonhard

So, it's really slim pickings anyway. Out of those guys Crayton or Logan are probably the most accomplished punt/kick returners.
