The Divas could be infinitely better if WWE would help them rather than just give them five minutes of air time and just let whatever happens happen and no real growth gets to take place. Kelly's been on the roster for like six years now and I see zero improvement (she couldn't even striptease any well on ECW). Look at Trish Stratus. When she first started she was pretty much what Kaitlyn is in the ring now (who I think has only started wrestling last year, give the girl a break), she was completely wooden in all areas and totally forgettable. But she was given plenty of airtime throughout her career, got the chance to show what she could do in a variety of storylines and on-screen roles, and as the years rolled on we could actually see the improvement taking place before our eyes, and she eventually became THE Diva of the last decade. She even seemed pretty confident in her charisma and mic skills.
Imagine how far some of these current "lesser" Divas could go if Vince gave even one of them the same support he did with Trish. A lot of them definately have the good looks (Layla, Kaitlyn), some of them have the charisma (Maryse, the Bellas), and some are just unique enough in their own way that deserves attention (Kharma, AJ). And shit, Nattie and Beth pretty much have all the pieces put together already, so there's no excuse for them to go to waste at all. Turning a blind eye to them because they aren't already developed enough to be entertaining is absurd when they all know they COULD be with a little support. Its not an easy business.
And if I had to guess, there's probably more female viewers now than ever so there's definately reason for the Divas to get airtime. No wonder the most fun they can have during a show is coo at Orton in all his baby oiled glory, or squeal when Cena takes his shirt off.
Point is, we know the Divas potentially CAN draw. Trish and Lita main eventing Raw a few years ago was not only refreshing, but a pretty fucking awesome match.
