Not much to disagree with in your post...I think concussions are at least one of the major concerns. Another is that Luke is elite...and as he's taken hits, he was losing speed and his ability to pass cover was not what it used to be. I just don't think he wants to play if he can't be elite. He was elite all through HS and all through college...and your'e right, what a joy he was to watch, and what a credit to the organization. He will forever be a Panther and only a Panther.
