Apparently Michael Cole's recent push is due to Vince McMahon. McMahon loves the way that Cole is playing his character and delivering creative's messages at the announcing booth.
Cole will appear on Smackdown! to help get over what the company needs them to with the new move to SyFy.
Some say that it has to do with Grisham's play-by-play while others are saying the main reason is to get the storylines over, including Cole's.
