It was mentioned elsewhere. I didnt get it from an insider site. So dont take it as gospel but it makes sense to me. Howard has looked great, Mason and Malloy have been solid. Griffin and Amerson arrive in the fall. Could be very tough for him to get the carries he would want.
It really sucks for him and unfair (if its Benson). New system, so he's lost a huge advantage as being the old competent dependable starter, and now would presumably behind several other guys. He wouldn't really gain anything transferring somewhere else either, unless he steps down a level. I hate it these guys are leaving, but as I've said before, for many of them its the last chance in their lives to play competitive football, and many people are willing to change schools to help stay on the field.
