While there's no doubt that the promotion has some of the best talents in the world, one startling issue with AEW has been its women's division.In comparison with NXT, AEW's women's division needs more depth and hence, this hinted signing at AEW Revolution could turn out to be a female star and who better than the former IMPACT World Champion, Tessa Blanchard.There have been rumors of her being in contact with both WWE and AEW, and while Tony Schiavone stated that he doesn't think that'll happen anytime soon, the statement could very well be a red herring. Tessa Blanchard joining the promotion would be a massive boost to its women's division.
