Yeah, but generally, it's a sliding scale of comp% and yards per attempt. That's acceptable, if not preferable.
But in many cases, it's that the stats simply don't exist. That's what bothers me. Tennessee had a badass RB back in like 1939 and in every blurb about him, it says he STILL has the all-time rushing TDs mark for the Vols. That's amazing! But are there ANY sources with number of carries? Yardage? No. Not on stat sites, not in UT's media guide, nowhere.
