I would say that about a similar amount of people saw it. I mean, I understand what you were saying, but this USC/ND game was hyped more than any game in recent memory. Personally, I was switching between that game and PSU/MICH. But with so many possible candidates in the USC/ND game (Leinart, Bush, and possibly even Quinn if he had led his team to a W in an impressive performance), I think that game garnered many viewers.
Either way, the race is between Young and Bush for now. If the season ended today, I would give it to Bush by a hair. (although the fact that Leinart is on his team could hurt him)
Thanks to Guttpuppy for the sig!
