The Colts released quarterback David Legree yesterday, and replaced him on the roster with free agent running back Mewelde Moore.
Legree was signed in late May as a free agent when the Colts released tight end Brody Eldridge. Legree was nothing more than a camp arm, filling in as Luck was in school and Mr. Irrelevant Chandler Harnish nursed an injury.
Moore, on the other hand, is an eight year veteran with some value still left. While he looked to be slowing down in Pittsburgh over the last couple of years, rushing for 3.4 and 3.0 yards per carry in 2010 and 2011, he rebounded in 2011 with a 7.1 YPC and a higher average yards per catch (9.5 vs 7.3 and 7.9). Moore is largely a third down back, with 102 of his 137 snaps coming on pass plays. He also knows the Bruce Arian system, having played in Pittsburgh from 2007-2010.
Moore, although having a limited sample size, still has some moves. The eight-year veteran ranked second among all running backs in Pro Football Focus' elusive rating, forcing nine missed tackles on just 33 snaps with the ball (pass or run). He averaged 3.86 yards after contact, fourth in the league. In pass protection, Moore gave up one sack and one pressure in 40 snaps, not great, but good (Brown had just two pressures on 68 snaps last season).
Moore will definitely compete for a roster spot, and can play special teams as well, although he's done it sparingly over the last two years. I can see him taking a roster spot from someone like Darren Evans. Whether or not he'd be a full-time third down back is questionable, but with the coaching staff planning on rotating backs out to keep them fresh, it's not hard to fathom a guy like Moore getting 40-50 snaps this year.
