Pittsburgh linebacker Joey Porter kept up his verbal barrage against the Seahawks, saying Thursday the Steelers will be so physical in the Super Bowl they will try to make Seattle quit playing. "We're going to try to tap out as many people as we can, I'm going to put it like that," Porter said at the Steelers players' final pre-Super Bowl news conference. "We're going to try to send as many people to the sideline as we can." Asked what he meant by "tap out," Porter patted the top of his head with his hand -- a sign that the player is tired or injured and wants to be taken out of the game. Porter's latest comments came a day after he ripped Seahawks tight end Jerramy Stevens' seemingly harmless comment that Seattle planned to spoil Jerome Bettis' retirement party by winning the Super Bowl. Stevens seemed mystified by Porter's reaction, calling it "ridiculous."
