Last season, Joe Johnson was the MVP and won the Championship with expansion team Triplets and first-time head coach Lisa Leslie. Johnson averaged a league-best 21.9 points and 3.9 assists per game, hitting multiple game winning plays. His incredible play saw him get a contract with the Detroit Pistons.
Now, Johnson is back for season 4 and looking to repeat with Triplets.
