VIDEO: Sixers force late-game turnover, tie it up with Ish Smith dunk

No one saw this coming.

With Saturday's game seemingly in the bag for the Golden State Warriors, the Philadelphia 76ers used an improbable 33-point fourth quarter to pull within striking distance of the defending champions.

With the scoreboard showing 105-103 and less than 30 seconds on the clock, Philly fans held their collective breath inside Wells Fargo Center.

And then, suddenly, Isaiah Canaan forced Klay Thompson to cough up the ball on a risky pass from Stephen Curry.

Ish Smith collected the loose ball and blasted off for a game-tying breakaway dunk.

Predictably, the crowd erupted in disbelief.

Unfortunately for the City of Brotherly Love and its feisty ball club, Harrison Barnes still had time to make a game-altering contribution of his own.
