Johnson filling in just fine for Smith

Posted by ESPN.com's Chris Low

Losing a player the caliber of Michael Smith for a big game is always a blow, but Dennis Johnson has stepped in for Arkansas in a big way.

Johnson already has 100 yards rushing through three quarters against a Florida defense that simply doesn't give up yards on the ground. Johnson has gained a lot of those yards on his own, running through Florida defenders and racking up the kind of yardage after contact you rarely see against these Gators.
