Plus, Kemba shot less than 40% in Big East play. He was still great, but if it was a regular season award, it made sense to give it to Jimmer.
I know that people, especially voters, don't put much overall thought into these awards, but I felt the disparity between the respective leagues they played in should have been taken into account. The Big East had much better players and defenses, and frankly3, the style was way more physical, the primary driver of Kemba's low shooting %.
In addition, I think the voters didn't take into account the complete player. Kemba was far, far better on the defensive end, playing almost exclusively man-to-man. Whereas Jimmer's relative ineffectiveness was hidden in BYU's zone.
Finally, Kemba was the primary cog leading a bunch of freshman and sophomores. He was the absolute focal point, with no other star players for most of the season (until Lamb emerged late). Jimmer had Davies. And more experience on his side.
