What TNA really need is a full reshuffle backstage, get rid of Dutch Mantell & Russo and bring in Heyman (although he's said he would reject TNA every single time).
Make new stars not bury them. Use guys like Nash, Steiner, Booker, Team 3D & Jerry Lynn (bring him back) to nurture/mentor young talent and put them over in feuds.
Get rid of some of the Knockouts, they have as more women wrestlers than WWE have and they only have 1 2hour show, theres just no need for continually bringing new girls in. Also just have some consistancy in the number of wrestlers, no bringing new people in every few weeks have some balance to it so they don't debut then a week later there an afterthought. WWE do it well, (baring ECW's talent initiative) they don't debut an awful lot of people per year which helps fans get used to them.
