Andrew Luck is obviously the most valuable player on this team. We saw what happened when he wasn’t healthy and a part of this team. It didn’t end well. But besides Luck, which player would the Colts suffer the most without? It’s an interesting question to consider.
Anthony Castonzo was that player early on last season. He didn’t come back until week 5 of the season after missing most of training camp. But the Colts offense still put up enough points without his services, so it can’t be him. It might not even be another offensive lineman.
