Here's the list so far. I'll update if necessary.
LB Patrick Bailey, Duke
C Doug Legursky, Marshall
QB Mike Potts, William & Mary
DT Martavius Prince, Southern Miss
DT Jordan Reffett, Washington
TE Dezmond Sherrod, Mississippi State
LB Donovan Woods, Oklahoma State
K Julian Rauch, Appalachian State
CB Travis Williams, East Carolina
WR Micah Rucker, Eastern Illinois
WR Dorien Bryant, Purdue
CB Roy Lewis, Washington
Woods is an intriguing selection. At 6'2" and ~225 lbs, he didn't play LB in college. He was a QB and a safety while at Oklahoma State. His brother Rashuan Woods, was a 1st round selection by SF in 2003. I'm not sure if the Steelers have plans to convert him to safety or pass -rush as a LB, or employ him in nickle or dime situations.
So much for finding DL help here. We'll see what, if anything, these CBs are able to provide. That sure is a lot of WRs coming in to battle for one, maybe two, spots. Are any of those guys KR threats?
