Im a New York Giants fan and I witnessed the most unlikely Super Bowl victory of all time. So if you want to count out the Celts now that is your decision. But the fact that were in the playoffs gives us as good a chance as everyone else. Whose to say the Cavs and Lakers make it to the 2nd round whose to say they make it out the 2nd round. No one actually knows you gotta play every game cant just assume the winner.
LETS GO CELTICS!!
The only thing unlikely about that Super Bowl victory for the Giants was them actually winning the Super Bowl, not so much getting there, and then, yeah, there was a ridiculously unlikely (lucky) throw and catch that ended the game.
Like somebody else said, though, you can't win the NBA Finals with luck even if you fight your way to get there.
