He's no Taylor, Chubb or possibly cook. But the guy is still better than most of RB's not named those guys. I know Mixon and Singletary are built differently but look at Mixon's stats this season 292 att, 1203 yrds, 13 td, 4.1 avg. I don't see how Singletary wouldn't perform better with the load he got the last 5 games this season
