You've already listed a few, and I certainly think Kligerman has the most to offer out of the ones you listed. I see more potential in Brian Scott and Colin Braun than I do it Trevor Bayne, but maybe that's just me. Also, even though Aric Almirola is in the cup series, I bet he becomes one of the greats, just as soon as he can nail down any kind of sponsorship on a decent car. Watching him court sponsors has become sad, but his racing ability is the best I've seen in a while. If his team can get through the truck season, I seriously expect a few wins, and a top 5 points finish.
