Are Managers Needed?

I was just thinking about some of the managers back in the day...Heenan, Cornette...etc...and was thinking if they could be useful in the current TNA product. The Naturals have Douglas, Roode has Ms. Brookes, and Abyss has Mitchell...but could more be useful? Granted...it was a way of getting certain talent over by pairing them with a manager/valet that could add some charisma. But are they needed...are more needed? Gals like SoCal Val and Christy Hemme would be perfect for such roles...if done properly. Val has a lot of managerial experience from the indies...and maybe...just maybe...those two ladies could help get some of the younger talent over...at least until a women's division started up. So...would it be worth it? Or does TNA have enough at this time?
