he's not built for this usage and its taking a big toll on his body this year. he's never carried this volume prior to this year. Has never accrued a 1000 yd rushing season. He's just the type of back you want to continue to have a nice complimentary to and keep fresh. You can argue all you want but AK is not really a back you want absorbing the volume as maybe some others do. But that is also helping prolong alvin's longevity hopefully.
