If we get Cribbs it means we don't HAVE to have PP returning punts. I still think he should, but he wouldn't have to do it all the time. If anything it would allow you to try to sneak PP on the field and see if you can catch the punter off guard and give PP a better show at a returnable kick.
Send Cribbs out there the first couple of quarter and then suddenly sneak on PP.
But we also have to remember that LSH was our KR man and I think that's what Cribbs would mostly be for, our replacement on kickoffs for LSH.
