The Eagles traded running back Mike Bell to the Browns for Jerome Harrison in a trade of backup running backs. It was clear the Browns weren't enamored with Harrison and didn't have faith in him being the lead back. Jamal Lewis was ahead of him most of last season despite looking anemic and even Chris Jennings got a chance before Harrison got the full workload in the final three games with 106 carries, including a 286-yard rushing game.
Even with that, the Browns drafted Montario Hardesty, but he tore his ACL in the preseason. When it looked like Harrison was back in the lead role, Peyton Hillis got the job and seized it. Harrison doesn't get a major boost in value with the trade. He will back up LeSean McCoy, who whill get most of the carries if he's healthy. Harrison is a better fit for the Eagles.
Bell has looked awful this season with the Eagles. The Browns are a power-running football team and that suits Bell more. Still, Bell will only see a good amount of touches if Hillis misses time. The value of each back doesn't change much, but both go to teams that are better fits for their running styles.
