Yes statistically they are close with the help of their home park. Notice the difference in runs scored at home/away for the Chi Sox as compared to those other good offenses.
And Youklis is def in the mix. His numbers are on the same level, no reason why he can't win it.
Also note there are still 30 games left in the season. Guys like Youklis and Morneau are proven players who have had great entire seasons. Quentin is playing his first full year in the bigs and first in the AL.
Morneau wasn't really known when he won his MVP. Heck, Fred Lynn won it as a rookie.
