Jeff Burton hasn't been with RCR for 10 years. He left Roush in 2004 and was replaced by Carl Edwards around the middle of that year.
RCR has a lot invested in the the Dillon kids. That could backfire in a big way if they don't perform as they hope. Havick's gone after this year and that leaves Paul Menard, who isn't bad, but he isn't great either.
Seemed like a good idea at the time...
