No that's not the case at all. Gameplan (owned by ESPN) picks up whatever games weren't worthy for ESPN, ESPN2, ESPNU coverage. When you are a .500 team in the SEC, they aren't interested in showing you on national TV unless it's a marquis game like UConn, Florida, UK, etc.
Last year we were a top 25 team so we got better coverage. That's just the world we live in.
Just win and all of the issues go away regardless of the personality of a head coach.
This is true if you're winning. But I think UT got more than it's share of TV time when Pearl was here because he was such a polarizing guy. People either love him (vol fans) or hate him (seemingly everyone else, especially Illinois fans). I think Martin gets UT back to premiere status, but he's never going to get the network love guys like Pearl get.
For being the official sponsor, Dish sucks! Switch your provider IMO.
