He wasn't drafted, but Josh Mauro is received pretty high praise from NFL Network.
The former Stanford linemen was ranked by the network's website as the sixth-best free agent acquisition.
Brian Fischer wrote that Mauro has the "size and motor to be an end in a 3-4 and could wind up taking over for Brett Keisel down the road if he sticks with the Steelers."
The 6'6'', 281 pound Mauro played in a 3-4 defense while at Stanford. His draft bio on NFL Network lauded his competitive fire, weight room ethic and ability to neutralize double teams. His detraction's include a "robotic movement"and minimal pass rush ability due to his marginal foot speed.
Mauro did enjoy his finest collegiate season in 2013. The then-senior tallied 51 tackles, four sacks, 12.5 tackles for loss, one interception and two forced fumbles.He posted 81 total tackles, 11 sacks and 21.5 tackles for loss over his four years with the Cardinal.
The Steelers addressed their need for depth on the defensive line early in the draft. They selected Notre Dame's Stephon Tuitt with their second draft pick and the 46th overall selection. The 6-foot-6, 322 pound Tuitt recorded 21.5 sacks that included 12 quarterback take downs while helping lead the Irish to the 2012 BCS National Championship game.
