Biggest surprises to me (in no particular order):
Jeff Gordon still being winless (although he has two solid chances coming up to end that winless streak..)
Ward Burton having won two races in one season
Jimmie Johnson 3rd in points
The struggles of powerhouses like RCR, DEI and to some extent RYR
Overall I think 2002 is one of the most intrigueing (sp?) Winston Cup seasons in a long time
