The best combo, unfortunately, was the team on the 48. Johnson and Knaus were the best, won't be beat, because nobody has been together that long, and been that successful.
I think Martin Truex JR and Cole Pearn have the best relationship because the trust each other, they respect each other and they are friends. I have never seen them be upset with each other in public. They are both easy going, maybe to easy going at times.
