VIDEO: Mo Speights blows fastbreak dunk

The momentum swing was right there, in the eager fingertips of Marreese Speights.

The Golden State Warriors had just forced shot clock violations on back-to-back Cleveland Cavaliers possessions. Klay Thompson had just cut the lead to three, and then Draymond Green poked an errant Matthew Dellavedova pass loose, with Speights corralling the loose ball.

Speights could feel it. Oracle Arena could feel it.

And then Speights blew the open fastbreak dunk, coming up a hair too short on his leap and hitting back iron.

That's a play the Warriors may look back on at the end of the game and rue. They entered the fourth quarter down 62-59 instead of 62-61, a marginal difference that could have been a game-changer in an incredibly tight Game 2.
