Doesn't matter at this point. There are younger more talented players. Guys that didn't even play last year would have passed him based on their natural progression (Gaynor, Reed, Campbell, etc).
I'm reading between the lines. Probably was told he wouldn't play much. We have a bunch of talented young lineman that will pass him in the depth chart. Smart move to free up a scholarship.
Thanks and best wishes to Mahoney.
