Just like how Buckhalter hasnt resigned with the Eagles but he's still the backup, I expect Rhodes will be back with Indy.
If Edge goes down or leaves next year, my money is on Rhodes or Mungro to take over for him. Rhodes has doen alright, but Mungro really impressed me the way he tore it up the few weeks he saw play in 2002. Like 150+ rushing yards and 2-3 TDs against an Eagles def that was ranked in the top rushing defenses at the time. If he's healthy, he could make a bid for playing time this year even with a healthy Edge I think.
