Nobody cares if the tournament games are works of art. Just like nobody cares if the Super Bowl is a dog of a game. They are watching "the event".
If it's close and comes down to a final possession (even if that possession, like most others in the game, is botched because the best talent was allowed to go directly to the pros like they should), it'll be lauded as a "thriller". And half the viewers (and those who had picked the winner on their brackets) will be ecstatic and remember it fondly, work of art or not.
Whereas, whether it's the Wisconsin loss or the Villanova loss of a few years before (which WAS a great game, and had our team's greatest players in a generation), either way, the losing team fans (us) wanted to vomit. It didn't exactly make anyone feel better that one of those games was at a higher level of play.
The Steelers first Super Bowl winning season was fairly mediocre, the team overall actually wasn't that fantastic especially the offense (they went through three starting QBs over the course of the season, and none did a particularly great job). And that Super Bowl is generally regarded as one of the worst. But no Steeler fan thinks poorly of it. It's a milestone game in their minds. Meanwhile, the SB where they lost to the Cowboys was kind of an exciting game, with Dallas roaring out to an early lead and the Steelers clawing back into it, marred unfortunately at the end by two dumb INTs, but generally a far more exciting game than Super Bowl IX. Does any Steeler fan feel better about that? No. Winning or losing is what is ultimately remembered.
