Agreed from a fan's perspective, but from a sponsors viewpoint I'd want top billing. Insight would not be as well known if it had been the Valley of the Sun Bowl sponsored by Insight because we'd all just refer to it as The Valley of the Sun Bowl. As it stand now, we can't stop referring to those games without muttering Insight.
The stupid thing about corporate naming rights is that they increase exposure, but they tell you nothing about what the company does or why you should patronize them. Has the Insight Bowl influenced your propensity of using Insight's products one bit? Do you even know what type of company Insight is? I don't, but I think it's some sort of internet service provider...and I've watched every single Insight Bowl since its inception. I don't know what Advocare V-100, Belk, or Beef 'O' Brady's do, either, but I've seen their bowls, and I've even watched the bevy of ads they show during the broadcast.
I understand that exposure means a lot to a firm, but you'd think they'd prefer to just buy up ad time during the TV broadcast in lieu of purchasing the naming rights to the game itself.
