That's not a guarantee, it's an argument

2011 Stanley Cup finals: Daniel Sedin of Vancouver Canucks guarantees Game 7 win - ESPN

Less than an hour after his team missed a chance to clinch the Stanley Cup in a blowout loss, Daniel Sedin was still confident enough to guarantee his Vancouver Canucks will beat the Boston Bruins in Game 7 on Wednesday night. "We're going to win Game 7," Sedin told the Vancouver Sun. "We're 3-3 and we won all three games at home and we have the fourth game at home," he said of the series, according to the report. "So we have the seventh game at home and we'll take that. We are confident." [...] Vancouver coughed up four goals in the first nine minutes [of game 6] and pulled starting goalie Roberto Luongo, who struggled mightily in all three games in Boston. "Like I said, it happened and we have to deal with that as a team," Sedin said, according to the report. "It's enough with the blaming and all that. We lose as a team and win as a team and we're going to win Game 7."

Babe Ruth, Joe Nameth, Mark Messier...Daniel Sedin? When the first three made their promises, in their various forms, they were throwing down the gauntlet. It was a challenge. A call to arms. What Sedin is doing is more along the lines of a fan's desperate (faulty) reasoning, and it's kind of pathetic. "We have won at home so far and the last game is at home and so we will win, because it is a home game, and we have won all the home games, so we will continue to do so. That is the pattern." QED?

I don't think so.
