It sounds as though Karl would like this to happen.
I can only hope the front office would think this would be potentially a huge win win for the team. From both the standpoint of fans getting to see the Mailman on the bench again, and Karl in so many ways would be the ideal role model and likely teacher for our young bigs. I can think of few players who better illustrated the drive to improve their game year in and year out. He might even inspire Jeremy Evans to add some muscle mass over his springs...
It will be interesting to follow this and see if anything occurs. Coach Corbin's initial response does not seem extremely favorable.
