NCAA grants Pittman 6th year

Just read this from an AP article and came over to see if it was posted.

It's mostly the same as the Baton Rouge article. This is great news for LSU's defensive front. Does this happen often? I can't say I remember having heard the NCAA granting something like this before. I'm sure there have been other instances, but there can't be that many.
