I think that Tennessee was the best choice for Rod.
First of all, it's in state and closer to home. Having his brother, Marsalous, there will help him ease into his freshman year. He'll get pretty good playing time at WR because God knows they need help there. I'm sure hearing that his brother was named the most improved player this spring will motivate Rod to step his game up and impress the coaches the way his brother did.
Hopefully Rod can be the player that makes that offense fun again and helps bring a championship to Rocky Top.
