Re: The commentary team?
Taz is just awful and the heel turn really hasn't helped.
Tenay is pretty awful - compared to his work at WCW or even earlier TNA years, he sounds completely disinterested, doesn't add to or build to the action on screen and misses 90% of what goes on. That said, now Todd is handling most of the play-by-play and Tenay is just chipping in with the odd comment, his contributions are generally more bearable.
Todd is a good addition to the team - good play-by-play commentary, competent. Can be a bit dry but given his current role in the commentary team that's fair enough. I'm happy with him.
Yes, I'd like to see West return - I think West and Todd would be a decent team. But what TNA really needs is a good colour commentator. In years to come I think Ray or Daniels would be excellent candidates for this. But in the meantime, I wonder if someone like Nash would be a good fit (I only say this as I recently watched the Paparazzi promos on YouTube and Nash was great on the mic and witty as Hell).
Failing that, I'd like to see more wrestlers guest-commentating - TNA doesn't do enough of this IMO, which is a shame when you have guys like Daniels, Ray, Aries, Magnus and Robbie E on the roster, all of whom are great on the mic. I suspect Ion and a few others would be good in that kind of situation, too, but they never get given the opportunity to hang on the mic for extended periods, other than Spin Cycle etc.
