Steelers Depot is keeping track of the Steelers' undrafted free agent signings. It's crucial to note that these signings aren't official yet and could change. But here it is for now:
DT Anthony Gray, Southern Mississippi
TE Weslye Saunders, South Carolina
DL Miguel Chavis, Clemson
WR Terrence McCrae, Ohio
C Colin Miller, Central Michigan (Steelers Depot notes that this one is unconfirmed)
WR Adam Mims, Furman
RB John Clay, Wisconsin
Michael Bean already wrote about the additions of Gray and Saunders, who are probably the most highly-regarded players on this list. It was no real surprise to hear of Saunders' signing, in particular, since the Steelers had been connected to him in the draft a few months back. Saunders was once a top tight end prospect, but he missed the 2010 suspension after being suspended and recently had surgery for a broken foot. The latest addition to the list is Clay, who posted pretty good numbers for Wisconsin, but had a horrible 4.83 40-yard dash at the NFL Combine.
