The problem is Cowboys fans want Aikman to be Cowboys fan or homer. Irvin is one, but he does it in a very clear way, i..e you know he is being a homer, and he doesn't pretend not to be a homer.
Aikman is not that. He has more responsiblity since he is Fox's No. 1 commentator. He has to be as objective as possible.
The problem is We fan's are myopic and want to only see Cowboys point of view and every call that goes against Cowboys is conspiracy etc. Aikman doesn't.
But if you hear him on Ticket interiviews ( here dallas locally on Thursday at 7.50 AM or so), you would know he is a fan of Cowboys, especially Romo. He defends Romo to a fault almost. He does get on Romo occasionally, but in a very constructive way.
So, its really foolish of fans to think Aikman is Anti-Cowboys. Its funny around the league from other team fans that he is Pro-cowboys. Like I said, Fans are myopic, and tend to view things very narrowly.
