He and Buck are both huge cowboys homers. They try every now and then to say something to make it seem that they are objective but when it comes down to it they always slip up and show their true colors. Those two are about as objective as PANatsFan talking politics, Lerners or PSU.
I'm pretty sure Troy and Tony are lovers, there's no other reason to explain his constant fellating of Romo. I don't know about Buck though, but Aikman is constantly suckin' off the Cowboys.
