VIDEO: Celtics' Crowder hits game-winning shot to beat Raptors, clinch 7th seed

The Boston Celtics are on some kinda roll right now, and they may prove to be a seriously frisky playoff opponent. 

Boston crawled back from a 15-point deficit against the Toronto Raptors on Tuesday night - despite losing Avery Bradley for the entire second half - thanks largely to relentless team rebounding and some outstanding two-way play from rookie point guard Marcus Smart. 

They got the ball with the game tied and just 3.1 seconds to play. And as they'd done against the Raptors just 10 days prior, the Celtics somehow found a way. 

This time, it was Jae Crowder playing hero. 

The win - the Celtics' fifth in a row - locks them into the No. 7 seed, guaranteeing a first-round matchup (for better or worse) with the Cleveland Cavaliers.
