It is March, and Portland visits the Grizzlies Wednesday night in FedExForum. When Griz point guard Mike Conley puts those things together, there’s a mixture of great memories and tinges of sadness. March means March Madness, and Conley can’t help but remembering how he and fellow freshman center Greg Oden led Ohio State to the 2006 Final Four (beating the University of Memphis in the regional finals) before losing to Florida in the national title game. “All of us will attest that going to the Final Four was one of the greatest times of our lives,” said Conley after Wednesday morning’s shootaround. “A lot of people don’t get to experience being on a team that played for a national championship. It was unbelievable.” Oden had 25 points, 14 rebounds and three blocked shots in the title game loss to Florida. He was the No. 1 overall pick of the ’06 draft taken by Portland, and Conley went three spots later at No. 4 to the Griz. Conley has become the starting point guard on a playoff team. Oden, thought to be the next great NBA center when he was drafted, was released last year by Portland. He played just 82 games in five seasons, because of three micro fracture knees surgeries.
