I think they should extend Impact to 3 Hours. That way there wont be fighting for air time the way it seems. Also, a second show that would be some what like Velocity. Where theres no promos, nothing but some under carders getting air time, and high lights of Impact. And it can air maybe inbetween tapings of impact. And would air at say, 10:00 on a Saturday or so.
Not only would it help guys like Homocide, Raven, Rhino, etc get noticed again, but it would also hype story lines more. The more commentators talk about rivalries and how great of a match it will be, people will get in there minds that its an intense rivalry. For example, the Shawn Michaels/ Undertaker match for Sundays WrestleMania is being hyped very, very well. Not only by the few promos by Michaels/ Undertaker, but by the awesome video packages being played 2-3 times each show. And the commentators constanly talking about the match. You dont always need wrestlers cutting promos to hype matches, and TNA needs to realize that.
