SEMIFINAL MATCHUPS

(1) BRANDON ROY VS. (3) ISAIAH THOMAS

Dickau's Details:

Roy, Garfield (2002)
“Although he never won ‘Mr. Basketball’ he put together a great high school career at Garfield. His career took off at UW where he became an All-American leading to be the 6th pick in the NBA Draft. He became an All-Star for the Blazers but knee injuries cut his career short.”

Thomas (Curtis, 2006*)
"One of the best scorers ever in the state despite his size. Strong, skilled, and shifty with the bounce - combined with his competitiveness has allowed him to have success at Curtis HS (left after his junior year for South Kent School in Conn.), UW and a lengthy NBA career."

RESULTS:

Note: Isaiah Thomas won the total vote across SB Live, Twitter and Instagram 317-174.

(4) KEVIN PORTER JR. VS. ZACH LAVINE

Dickau's Details:

Porter Jr., Rainier Beach (2018)
“As explosive as the state has ever seen. He could score in literally any way at Rainier Beach. One season at USC before being drafted in the first round of 2019 NBA Draft where he looks to have a long and promising career ahead of him.”

LaVine, Bothell (2013)
“Supreme athlete who could really shoot it – played at Bothell High School before heading to UCLA. Left after one season and with his work ethic has carved out and incredible NBA career.”

RESULTS:

Note: Zach LaVine won the total vote across SB Live, Twitter and Instagram 334-160.
