Cooper of Ohio, Michael Eric of Temple, Zeke Marshall of Akron, Trevor Mbakwe of Minnesota, James Southerland of Syracuse, Rodney Williams of Minnesota and Khalif Wyatt of Temple.

Motum, a 6-foot-10 forward finished his senior season in 2012-13 leading the Pac-12 in scoring for the second-straight year with 18.7 points per game, while ranking fourth in the league in conference games only with 17.4 points per league game.
He scored at least 11 points in all 32 games this season and reached double-figure scoring in 32-straight games. With 6.3 rebounds per game, Motum ranked 16th in the conference, while he was fifth in minutes played with 35.3 minutes per game. He had 5 double-doubles during the 2012-13 season, including in two in his three final games.
In WSU's final regular season game, Motum moved into fifth on the WSU all-time career scoring list and finished his career with 1,530 points. Motum's 597 points this season ranks sixth on the single-season list.
This past season Motum also became just the 12th Cougar to score 1,000 points and grab 500 rebounds in his career as he has 539 career rebounds. Motum was named the Pac-12 Player of the Week both Dec. 10 and March 11.
Last season Motum was named the Pac-12 Most Improved Player and first team All-Pac-12. This past year he became the ninth Cougar to earn second team all-conference honors as it marked the 14th time a WSU student-athlete has earned the accolades.
He joined Jim McKean, Don Collins and Kyle Weaver as the four Cougars to earn both first team and second team all-conference honors in their careers. WSU has had a representative on one of the first two all-conference teams each of the last seven seasons.
Motum was also named to the United States Basketball Writers Association (USBWA) and National Association of Basketball Coaches (NABC) All-District Teams in March.
A new format will be introduced to the OPSL this summer, with two extra teams and an extra day added to the slate. Under the new format, each team will play five games with a championship game being played on the final day of the league.
A point system will establish the standings leading up to the final day, with seven points awarded each game based on: three points for winning the game and one point for winning a quarter (in the event of a tied quarter, each team will receive 0.5 points).
In the event of ties in seeding heading into championship day, three tiebreakers will be in place; 1) total point differential; 2) total points allowed; 3) coin flip.
