I think Gore has the better value over the longterm. However, the ability to lock up the Indy running game is very good as well. Rhodes is just a few years removed from a 1,000 yard season and should see some action this season.
While the insurance value is high, I still have to lean in favor of Gore as Barlow has pretty much proven that he can't get the job done and it is only a matter of time for Gore to handle a very big share of the load as he began to do towards the last part of the season.
