As in any sport, team chemistry is a very important part of a successful season in NASCAR.
Even a Chase-caliber team won't go anywhere if the wrong driver is behind the wheel, as Penske Racing and A.J. Allmendinger showed earlier this season. But at the same time, even a very talented driver can only do so much with a shorthanded team, as Kurt Busch can tell anyone about his time with the underfunded Phoenix Racing.
As the Sprint Cup silly season starts to kick into high gear, this is the right time to think about drivers who just aren't clicking with their current teams and might need a change of scenery.
Most of these drivers have the benefit of expiring contracts at the end of this season and will probably look elsewhere for 2013 and beyond—though there are some notable exceptions.
Without further ado.
