Giants center Shaun O'Hara voiced his displeasure with disgruntled wide receiver Plaxico Burress on Thursday, according to The New York Post. Burress reported to the team earlier this week, but has refused to practice with his teammates until the Giants give him a new contract. Asked if it was difficult to deal with players putting "business matters" ahead of the team, O'Hara responded, "Whether players like it or not, this team is going to move forward. You're either with us or you're against us." "I think there's a right way to do things," O'Hara said. "And I've always felt that, as a player, you go out there and you put your best foot forward and as long as you're giving 100 percent effort every time, you'll be taken care of."
