Legit question. Is there anything at this point in which can save TNA or have they forever lost their number two spot?
They will always be a solid #2 or #3. There's nothing that can fill the gap, and as long as TNA has the Panda Energy machine behind it, it will be around. ROH has the power to do so, but they have a much smaller owner/financial backer. Meaning TNA will always make the bigger signings, run the bigger venues and have bigger TV slots. Of course, in the last few years it's been pretty much the opposite. But TNA is willing to put it all on the line for their TV Guide Channel, slot. I'm not exactly sure they'll be out of buildness since they've already been doing better numbers since the move. Might be a revival for TNA.
As for what can save them, I'd say a much more respectable product. You look at TNA and you have Hernandez breaking laws and running amuck. Then you have talents who aren't even with the promotion doing another 5-6 months worth of TV. Then you have 80% WWE guys. Then you have horrible business deals. Then you have the Animal Planet deal. Then you have the constant flush of talent. The rumors of horrible pay and no pay. Low morale. Low attendance. Low ratings. Very thing roster. It's a combo of things that makes fans and wrestlers alike lose interest and faith in the promotion. They need to stop the months upon months of TV at a time. You'll have a WCW/Sid fiasco. They need to have a solid roster; not a fluctuating one that is here and gone within a months time. You need to have a much more original roster. I like that they're giving guys like Trevor Lee and Everett, shots at the big time. Maybe they'll stop being the butt of the jokes.
And for once can they have a solid business deal. One day, they're touring India. Another, they're postponing. Another, they're touring. Another, they're postponing. It's so stupid. I haven't watched a full episode in over a year, and it's quite sad, since I felt that they were getting a revival.
tl;dr - they are always going to be a #3 or #2 as long as they're around. In America at least.
