Drew's story is an incredible tale of how a change of character can do wonders for a Superstar.
Drew McIntyre was a part of "3 Man Band", who used to wrestle occasionally on Raw and regularly on Main Event. Soon, he was released and went to TNA. There, he turned into a muscled up giant who looked genuinely terrifying.
Drew was called back to WWE, groomed for a while in NXT and debuted as The Scottish Psychopath on Raw. The push didn't go anywhere and he's currently part of a three-man team alongside Lashley and Corbin. The trio has been sneak-attacking a string of babyfaces since months and McIntyre's aura is fading quickly.
A move to SmackDown could do wonders for him. He needs to destroy some babyfaces on the blue brand over the course of the next several months, and come back to Monday nights, ready to challenge for the Universal title.
