Do you think Kyle Busch will finish his Cup career at JGR?

No eventually like all teams do they will lose there edge. One day (but not for a while) Hendrick, Rousch, and Gibbs will be surped by other teams. If you don't believe me then look at the once mighty Wood Bros, RCR, and Petty Enterprises. Kyle has another 20 years in him easy. Kyle will eventually move to the greatest team in that era which could be MWR or Stewart Haas.
