Suck for Luck is actually smarter than what the Bills are doing. If Miami gets Luck and the Bills miss the playoffs, the Dolphins win. (They actually win regardless if they can get Luck but at least we'd have something to be happy about, too). If the Dolphins barely miss out on Luck, that'd be a hilarious failure, though.
Time will tell. Luck will win a Super Bowl before the Bills do, but there was no point in rooting for Luck past the Game 1 demolition of the Chiefs.
