Devin Bush is generating a buzz this offseason. The Michigan product has good linebacker skills and has athleticism that showed up in his combine performance. Although I was not impressed with his coverage on tape, I think his 4.4 range speed is an indication that he can develop in this area. He will be asked to play that Mack Linebacker role and we know from the Ryan Shazier days how important that is.
Vince Williams will be the Steelers thumper and he has done well in that role. He has even made it to the Pro Bowl playing that role.
