Vince McMahon has the last word in everything that goes on in WWE. So if he loses interest in a Superstar, it is unlikely he will be pushed again anytime soon. This is the case with a current WWE Superstar.
On Wrestling Observer Radio, Dave Meltzer was asked if Paul Heyman could push EC3. Meltzer said that it was unlikely as Vince McMahon already made up his mind. Meltzer’s opinion is that Vince McMahon gave up on EC3 very quickly. They also tried putting him together with Drake Maverick to recapture their feud in TNA, but Vince “hated” that as well. Meltzer also does not think Paul Heyman was the one to give up on EC3.
Fans were looking forward to seeing what he would accomplish in WWE. However, they are surely disappointed at the turn of events. McMahon simply lost interest in him far too soon. We will have to see what’s in store for EC3 once he returns.
