While the on court action climaxed in June when the Spurs swept in the Finals to claim the Larry O'Brien trophy, off the court the NBA has seen its fair share of excitement all summer long. As opening night readily approaches here is the scoop on what has changed since the last time your favorite NBA players took the floor.

Player Movement

After New York finished last season with 33-49 record, coach Isiah Thomas shook up the New York roster trading Steve Francis and Channing Frye for big man Zach Randolph, Fred Jones and Dan Dickeu.

The big three are now in Boston. GM of the Boston Celtics, Danny Ainge turned Ray Allen and Kevin Garnett into Celtics. The two superstars will team up with Paul Pierce as the three pursue their first championship together.

Although USA already clinched a spot in the 2008 Beijing Olympics, they claimed the gold in the FIBA Americas tournament in Las Vegas. They beat Argentina in the Finals 118-81. LeBron James led the pack with 31 points followed by Dwight Howard with 20 and Carmelo Anthony with 16.

NBA Draft

The 2007 Draft distributed top talent across the NBA. With the No. 1 pick, Portland chose Greg Oden, Ohio State's star freshman. Following Oden, Seattle selected swingman Kevin Durant. Since Oden is out for the season (cartilage damage to right knee), many anticipate that Durant will be the recipient of the Rookie of the Year accolade.

Summer League

While the 2007 summer league in Las Vegas hosted mostly rookies and sophomores, third year Nate Robinson participated and earned league MVP. He averaged 18.8 ppg and an impressive 6.0 apg.

Rookies Aaron Brooks, Glen Davis and Kevin Durant also shined.
