One of the main problems last year in addition to the run defense issue, was the short yardage running issue at the goal line, and on third and fourth downs. White at 235 pounds can get into the end zone, and can convert on short yardage.
The addition of some larger offensive line men like Zane Beadles will also help.
Buckhalter can also run inside. Moreno is a speed rusher, and he often requires a hole to run inside. The Broncos need White to run over people if necessary to get first downs, and touch downs.
White posted 1,110 yards for the Titans in 2007, and 15 TDs in 2008.
