While the Pats have only drafted Mike Elgin out of Iowa, they have taken 12 other Players whom played against Iowa during their college tenures. Those players are: Ellis Hobbs, David Thomas, Shawn Crable, Laurence Maroney, Eugene Wilson, Matt Light, Tom Brady, J.R. Redmond, Greg Robinson-Randall, David Nugent, Christian Mortan , Guss Scott and Marquise Hill.
That's the list I had compiled up to the 2008 draft. I hadn't researched the 2009 Draft to see who Ferentz could have commented on from that Draft.
