Colts with large amounts of cap space, still have not address the center position. Alex Mack may be a long shot, but we still need a quality veteran. We cannot expect the line to be improved with Costa who played in 3 games last year, and Holmes who is a 4th rounder with 3 games experience. That is not really surrounding Luck who every team in the NFL would love to have, save for a few teams, with much talent. I would love to see what Luck could do with more time in the pocket, with our receiving corps that could be very dangerous. Grigs get a real quality center please, lets not try and save a few bucks when comes to Lucks livelihood.
