Well, not by their political contributions, apparently. Per this article in the Village Voice (no, I don't read it regularly!) back in January on the political contributions of the NFL teams then still in the playoffs:
The Pittsburgh Steelers were the most generous at $89,430. The vast majority of it came from the Rooney family (the owners), and most of their largesse went to the GOP or a PAC called the North Side Good Government Committee. Two players from the Pittsburgh Steelers are in the books as donors: Linebacker Clark Haggans gave $5,000 to the Democratic Congressional Campaign Committee. Back-up quarterback Tommy Maddox gave a grand each to President Bush and the RNC. Across the field from Maddox this weekend will stand Peyton Manning, an opposing quarterback but a political like-mind. Manning wrote a $2,000 contribution to Dubya. Manning's Indianapolis Colts organization as a whole gave more than $64,000, with the family of owner James Irsay directing most of that coin to the GOP.
