I agree. I find there are two types of running backs, those that will take something small and turn it into something big, and those that will take nothing and turn it into something small.
Chevy, Cobb, Thigpen, even Lumsden, were the former types. Give them a little space, get them outside, throw a screen, basically find a way to get them out into the open in any way and they’ll take it to the house. All talented players but you have to create that space for them so they can show their stuff.
My two favourite backs, Troy Davis and Ron Williams, would take the ball, disappear amongst the line and through an act of magic, re-appear marked down 7 yards further down-field. These guys are a special breed.
Walker’s doing a good job and if it ain’t broke, don’t fix it, but I’ll admit that I’d be more confident giving Cobourne the ball when we just want to run it up the gut for 3 yards.
