As their current starting QB Ben Roethlisberger awaits word on his probable suspension, Pittsburgh has traded for another quarterback that could wind up starting on opening day, according to ESPN NFL Insider Adam Schefter. The Steelers acquired their former quarterback Byron Leftwich from Tampa Bay for a seventh-round pick in Saturday's draft, according to a team source. Leftwich could well be the Steelers starter in their regular-season opener. Pittsburgh also has quarterbacks Charlie Batch and Dennis Dixon, but Leftwich knows the offense and organization well. He backed up Roethlisberger in 2008 when the Steelers won a Super Bowl before he left to sign as a free agent with Tampa Bay. The latest NFL trade also leaves Tampa Bay with 12 picks in this weekend's draft, which ties them with the New England Patriots for the most in the league.
