I really should re-phrase the above anyway... because halfback, 5/8th and fullback as far as attack goes are becoming more meaningless year on year. I guess the only thing a fullback doesn't do that a 5/8th might is play first receiver more often. I can't see that happening much while Pearce is healthy, though... in fact it shouldn't happen while Pearce is healthy.
We'll see how it goes, anyway. The only person who can really let us know how it's going to go is Kalyn when he takes the field... so we'll just have to wait and see. He has the skillset to make a fist of anything thrown at him.
