Safety Anthony Smith not only thinks the Steelers have a chance Sunday to beat the undefeated New England Patriots, he guarantees it. "We're going to win," Smith said after practice yesterday. "Yeah, I can guarantee a win." Smith, a hard-hitting free safety who replaced injured Ryan Clark as the starter midway through the season, said he's not worried about providing any motivation for the 12-0 Patriots. "Now we have our swagger back on defense and we're playing great ball, and they're playing great on the offensive side, too," he said of the Steelers. "I think we have a real good chance to win the game and we will win the game." Not only that, he said while New England's receiving corps of Randy Moss, Wes Welker and Donte' Stallworth is good, those three aren't as good as Cincinnati's T.J. Houshmandzadeh, Chad Johnson and Chris Henry. "I think we were facing great receivers last week, too, and we shut them down," Smith said. "Those three guys, I don't think it gets much better than Cincinnati's corps of receivers. We've already seen the best."
