There's no reason why we can't use both. We need to man up and play new era football. The days of an every-down back are gone. All the good teams on the ground have two guys to use.
Tennessee Titans -- LenDale White / Chris Johnson
Atlanta Falcons -- Micheal Turner / Jerious Norwood
Carolina Panthers -- DeAngelo Williams / Jonathan Stewart
New York Jets -- Thomas Jones / Leon Washington
Minnesota Vikings -- Adrian Peterson / Chester Taylor
New York Giants -- Brandon Jacobs / Derrick Ward / Ahmad Bradshaw
Look at San Diego struggling with LaDainian Tomlinson. Look at St. Louis struggling with Steven Jackson. These guys are elite running backs, but they have nobody behind them.
Seriously. Ryan Grant and Brandon Jackson have the potential to be just as good.
