Various media outlets around Toronto are reporting that Dallas Mavericks assistant coach Dwayne Casey will likely become the Toronto Raptors new head coach.

Casey's role in orchestrating the Mavericks defense of Miami in the NBA Finals may have pushed him ahead of Lawrence Frank, the other finalist and an assistant coach for the Boston Celtics. The Raptors, who finished last in the league in defensive efficiency, are looking to significantly improve on that side of the ball.

Casey has previous head-coaching experience in Minnesota, where he compiled a 53-69 record in the 2006 and 2007 seasons.
