Dana White wants Anderson Silva to move up to light heavyweight permanently if and when he defeats Chael Sonnen and Vitor Belfort. He would vacate the middleweight title in the process. Obviously this move would be made easier if Shogun wins tomorrow.
If Shogun wins tomorrow, I'd like to see Anderson move up after fighting Sonnen. His days @ MW are over, there are very few interesting fights for him left there. Time for him to clear out the LHW division.
