Wiedmer: Could a split fingernail decide the NBA Finals?

By midnight Thursday night, the National Basketball Association will either have a new champion or a seventh and deciding game on tap for Sunday evening.

Let Golden State win inside Boston’s TD Garden on Thursday and the Warriors will win their fourth championship in eight years with the three-headed monster of Steph Curry, Draymond Green and Klay Thompson.

Such a victory would do much to cement the argument that the Warriors deserve mention as one of the NBA’s best dynasties ever, and make them at least as likely to repeat a year from now as anyone else is to dethrone them.

However, let the Celtics win the next two – as they did in climbing from a 3-2 deficit against then-defending champ Milwaukee in the Eastern Conference semis – and not only will Boston edge past the Los Angeles Lakers for most world championships all-time, going ahead 18-17, but the Big Green will almost assuredly become the favorites to repeat in the spring of 2023.

So who wins this year? In a series in which every game has been decided by double-figures to date, is one team appearing to get stronger as another weakens?
