Free agent forward Josh Harrellson, who was waived by the Houston Rockets earlier this month, has worked out for the Miami Heat. With one roster spot still open, it’s believed Miami will bring in a big man to help improve its frontcourt. Via ESPN.com: “Harrellson averaged 4.4 points and 3.9 rebounds while shooting 33.9 percent from downtown last season as a reserve big man for the Knicks before being traded this offseason to the Rockets in a package for center Marcus Camby. A rare rebounding big man who can stretch the floor, Harrellson joined Minnesota Timberwolves forward Kevin Love and Milwaukee Bucks forward Ersan Ilyasova as the only qualified players last season to average over nine rebounds and make at least one 3-pointer per 36 minutes on the floor. Though he lacked the height of a traditional center, Harrellson primarily backed up Knicks center Tyson Chandler last season. After signing 3-point shooting wings Ray Allen and Rashard Lewis, Miami is aiming to fortify its front line that consists of Chris Bosh, Joel Anthony, Dexter Pittman and Udonis Haslem.”
