Like all teams, JGR is looking for Championships. Truthfully, Bobby's star was falling. His championship days were over. The fans (me included) loved him though. Wrt the young drivers, if they don't start winning their fair share of races within the first 3-5 years, they're gone. JGR is always chasing the latest shiny object. I'm really surprised they kept Joey as long as they did.And to Bobby Labonte.
We can also add Daniel Suarez, Eric Jones, and Aric Amirola to the list. That's just at the Cup level.
I think Tony put a curse on the #20 after he left.
