I don't think the weight is that big a deal, just pointing out that there seems to be a trend toward smaller drivers in NASCAR.
FYI, Robby is listed as 5-10, 180 officially, but as I said recent photos I've seen of him kind of make me think he's a wee bit stockier now.
So, the heaviest guy you listed is winning more poles than anyone. He's not winning any races this year though. Maybe those smaller guys do have an advantage over the long haul.
Since this thread concerns weight in relation to results on the track I have a question. A few years ago Newman was winning a lot of races on "fuel conservation". My question is, if weight makes a difference in fuel consumption and Ryan was winning those races, where in the car was he hiding the extra fuel and why couldn't NASCAR find it? ;^)
