Looking at the TNA roster, I can see a lot of guys that could really benefit from working with a Midcard title.

Chris Harris
James Storm
Robert Roode
Eric Young

All of them are over right now, and all were either just invovled in or just got out of a hot feud. Harris & Storm just stole the show at both the PPV and a recent Impact, and Roode/Young might be the best angle in TNA right now. However, with the main event scene so crowded right now, it would be nice to see these guys go for a singles title, and a TV title would do wonders for them, especially for guys like Eric Young & James Storm who is suspect will be over for quite a while, but will never really make it to that main event level that Harris and Roode have a better chance of.

Looking at the roster there are even some former World Champs that could go for the title

AJ Styles (1st ever TNA Grand Slam Champion! They should create a Midcard title just so AJ can have that title)
Rhino
Raven
Ron Killings

These guys fit into the main event scene well at one time, but once again its a little crowded at the top (Sting, Angle, Christian, Joe) and it would be cool to have a midcard title for these guys to go for in the early stages just to make the title feel more important right off the bat.

And then looking at the X Division portion of the X Division portion of the roster Jerry Lynn & Senshi are both very talented indivduals that could easily mesh with the heavyweights and go for a singles title if given the chance. And do I even need to bring up Christopher Daniels, who is getting his chance to mesh with the heavywieghts now in a feud with Sting.

The only roadblock that would prevent a Midcard title right now is only having a one hour show. Hopefully once they get that second hour, they can focus on creating a TV title or a US title or something.
