VIDEO: Kyle Lowry vehemently rips water bottle from manager's hand

With his team up big on the scoreboard against the Boston Celtics Friday evening at the Air Canada Centre, Lowry, still riding his adrenaline high, viciously grabbed a bottle of water from one of the nearby managers, leaving him visibly shook.
