Depends on what he means by "competing with"
TNA is already "competing with" WWE in some sense. If you are a fan of wrestling and hate WWE, TNA is growing to the point where those types of fans are more and more likely to turn to TNA as an alternative. This forum is a perfect example of that. When I joined the first thing I did was make a discussion thread for TNA in Wembley last year. We had no TNA section. hell, we had no other wrestling section. I posted that motherfucker in the locker room. And then we got the other wrestling section as more people began to watch. Eventually it became popular enough to have it's own section, and now the section is pretty damn busy.
But we started with like a 3 or 4 man crew who would follow TNA regularly, and now we must have at least 20 or so who keep up with TNA. The bigger TNA gets and the more WWE fucks around the more people who start to say "maybe I'll watch Impact this week and see if I like it"
