PHOENIX (AP) — When the conversation turns to Super Bowl losers, the Bills and Vikings immediately come up.Both are 0-4, Buffalo managing the feat in consecutive seasons.The Broncos were in that sinking ship until John Elway completed his Hall of Fame career with two championships.The Patriots? They own a share of the short-term success mark in Super Bowls: three in a four-year span. They've been back twice since their previous championship victory and failed to add to their collection.Should they lose to Seattle next Sunday, these Patriots will become three-time losers, too.
