The "behind-the-scenes" reason for the MVP draft to RAW coincides with the Rey Mysterio move to SmackDown. WWE simply wanted to switch the U.S. title to the RAW "second highest singles champion" and the same for the Intercontinental title on the SmackDown! side.
Same can be said for the two female-singles titles in WWE right now. Melina was moved to SmackDown! so the brand would now have the "Women’s title", whereas RAW now is home to the "Divas" champion.
