Jackson to backup Green?

Here's this nugget from the ABJ:

James Jackson is listed as the second-team running back. Jamel White will play on passing downs, but it appears Jackson will spell William Green on regular downs.

This is news. I think it's a combination of two things. One, James Jackson has had a nice preseason and is running hard. He doesn't have lightning speed but he's hitting the hole with some authority and there hasn't been any drop off when he's been in the game. If he plays like this during the regular season he'll be a nice asset for the team. Two, I wonder if Jamel White is still slowed somewhat by injury. Everyone says he is recovered and that may be true, but it seemed to me during the preseason that he was lacking last year's aggressiveness. It could be that this is more mental than anythinig else. In either case, be glad Jackson is playing well and look forward to "Track Meet" regaining his position in the comng weeks.
