-- Mike Wallace & Limas Sweed Interchangeable at No. 3 WR --Sat Sep 12, 2009 --from FFMastermind.com#The Pittsburgh Post-Gazette reports while it appeared rookie WR Mike Wallace moved ahead of WR Limas Sweed as the team's No. 3 receiver based on Thursday night's game against the Titans, he has not. Wallace took nearly all of the snaps as the third receiver, but it wasn't by design. OC Bruce Arians said he even told Sweed after the game that he didn't mean to keep him on the bench as much as he did. Arians wants to involve Sweed, last year's second round draft choice, in the offense this season, especially after his productive preseason. And he insists Sweed and Wallace are interchangeable in that role, meaning either one could end up getting most of the snaps in a given game.
