Edgerrin James has had to navigate some treacherous terrain in his career, but never in territory that felt this unfamiliar.
Call it the land of aging running backs who feel they're being phased out for younger, shinier models. In the Cardinals' case, that model is Tim Hightower.
"It's cool with me," James said Monday when told Hightower could get more snaps. "That's the way it was heading, anyway."
...
Before we get too far ahead of ourselves, Cardinals coach Ken Whisenhunt never said Hightower was supplanting James. He simply said Monday, when asked, that he is open to the possibility.
"I think we've shown we're going to play with the players that we feel give us the best chance to win," he said. "We've done that with the quarterbacks, we've done that with linebacker, with the offensive line.
"At a point we feel Tim gives us the best chance to win, then absolutely. Just don't think we'll judge it based on just yesterday's game. It's a process."
After averaging 20 carries in the Cardinals' first three games, James has carried nine and seven times, respectively, in the past two.
Hightower carried seven and six in those games but has six touchdowns overall to James' three.
