if dynasty barnett...
if not, they are all very close... i might say peterson, but i have a hunch barnett could be cleaning up a lot of slop this season behind suspect interior DL. than again, the league best DT tandem of stroud & hendo is one reason peterson gets kept clean & is freed up to fly to ballcarrier & roam sideline-to-sideline with relative impunity.
barnett may be an ascendant player & could be getting better... and he is already about as good as these guys without accounting for that... which may recommend him.
peterson while older, could be possibly thought of as ascendant player also in sense that he was WLB with colts, & was claiming to still be getting better as he learned nuances of new position as MLB with jags.
