I wouldn't hire any guy wearing a Steelers tie.
Or Eagles, Redskins, Giants, 49ers, Packers ties.
I wouldn't hire anyone wearing any NFL tie.
My wife won't even wear her wedding ring to interviews because of the stereotypes. After she has been hired, people commented on it, and said it was a smart move. It's just the world we live in.
Any tie with an "emblem" of any kind really isn't appropriate for a job interview.
Get a plain blue or red tie and wear it with a blue suit. No one can ever say anything bad about that.
