He's very rarely wrong.
He may have insider info leading him to believe Coleman will be 2015's center. The coaches went way above and beyond giving Coleman chances to be a starter in 2014. Reminds me of how J Johnson was put into games ahead of others who clearly outperformed him. For some reason the staff really believes in those 2? Based on play in games in 2014, there's no way Coleman pushes Crowder aside.
