The last time Layla was on TV was that bullshit mixed tag with Khali.
The last time the divas' had a singles' match on TV was the AJ vs Layla match on June 30's Smackdown, they've had some mixed tags, but that's all. The last time they had a singles match on Raw was May 21.
Yeah, they never get any reaction, but so little effort has been put into the division that there's no reason for the fans to care. It's not Layla's fault or any of the other ladies (now that Kelly's gone), it's all on WWE. If they can actually put anything resembling effort behind the division it could be a pretty good ratings draw for them.
If WWE has this little confidence in the Divas' (not letting them wrestle for over a minute if they get on the show at all), then why do they bother employing them?
