The 49ers continued to fill needs Monday, when they dealt a fifth- and seventh-round choice this year’s NFL Draft for Browns quarterback Colt McCoy. It means the 49ers quarterback cupboard is now full with starter Colin Kaepernick and backups Scott Tolzien and McCoy. The 49ers also get a sixth round draft choice in the deal. McCoy became a star at the University of Texas and finished second to Sam Bradford in the 2008 Heisman Trophy race. However, he faltered as a starter in Cleveland. In three NFL seasons, he compiled a 74.8 passer rating with 21 touchdowns and 20 interceptions. The last time we saw McCoy in a significant game, he was getting concussed by Steelers linebacker James Harrison in the 14th game of the 2011 season. McCoy’s inability to win a starting job prompted the Browns to draft Brandon Weeden in the first round of last year’s draft.
