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.
