Several weeks back in a Hurry Up (12/1) after Walker had decommitted, Birm wrote this:
Over the summer, the critically acclaimed short story "Decommitment Season: You Chose Too Early" came and went, claiming a number of awards such as "Most Likely to Wear Another Teams' Shirt to Your School" and "Maybe You're Not as Good as We Thought."
Obviously the first reference, wearing another team's shirt, referred to Hall. I was wondering if the second one, "Maybe You're Not as Good as We Thought," was a subtle explanation of what played out with Walker. Maybe as his senior year progressed, our coaches became increasingly skeptical of Walker's abilities to be a game changer at the next level. Essentially they discovered he wasn't as good as they thought or as good as his lofty recruiting ranking would indicate. Thus they felt less compelled to jump through the necessary hoops to coddle his expectations, which in turn led him to look around and eventually decommit.
I have ZERO insiders information. Just my humble speculation
