John Nash, whose contract is set to expire in a month, won’t be back as Portland’s GM.

John Nash made his share of mistakes. With four first-round picks the past two years, his haul of Sebastian Telfair, Viktor Khryapa, Sergei Monia and Martell Webster left a lot to be desired — especially since Chris Paul could have been a Blazer. But Nash had his share of positive moves as well, including free-agent bargains Joel Przybilla, Steve Blake and Juan Dixon.

Unfortunately, those low-wattage additions were the only kinds of moves he could make because his hands were tied behind his back. With owner Paul Allen and team president Steve Patterson calling most of the shots, Nash was left to tinker around the edges. With such a muddled management structure, it’s no surprise that the Blazers sunk to the bottom of the NBA standings this season.

The team’s president, Steve Patterson, will serve as interim GM. The first thing he should do is read my offensive blueprint for the Blazers.
