Don't blame AJ, really. He sees Ethan Wolf, Alex Ellis, Neiko Creamer, & Joe Stocstill all around him, most in front of him on the depth chart...and then sees young incoming talent joining the squad in the form of Will Jumper and Eli Wolf...and then sees gifted athlete Jakob Johnson shift into the position ... he just read the tea leaves and figured out he probably wasn't gonna get nearly as much play time as he was looking forward to.
So he's off to find a greener pasture with less bulls ripping up the earth. Makes sense, from his perspective. I wish AJ the best, wherever he lands.
