In a few years, TNA may not even be around anymore if no one else in management ever realizes that Jeff Jarrett as World Champion, along with bringing in older "name" talent, doesn't draw, and that building up younger, homegrown talent along with former WWE wrestlers who weren't pushed as much as they should have been will bring in more success for TNA.
That would probably help WWE improve eventually if TNA can realize the mistakes they're making right now.
