ESPN and its sources report that Don Nelson may be willing to come back to an NBA bench, in Minnesota of all places (now that there’s a coaching vacancy.): “Portland Trail Blazers assistant coach Bernie Bickerstaff, for the moment, is the only known contender for the Minnesota Timberwolves’ coaching vacancy. But a potential Wolves candidate with even more experience unexpectedly surfaced Tuesday when NBA coaching sources said that Don Nelson — the winningest coach in league history — is open to a return to the bench and intrigued by the talent on Minnesota’s roster. Wolves president of basketball operations David Kahn said at a Tuesday press conference to formally announce Kurt Rambis’ dismissal that he wants an up-tempo coach to take over, particularly with Spanish point guard Ricky Rubio — drafted with the fifth overall pick in 2009 — scheduled to finally join the team when the lockout ends. Nelson is certainly well-acquainted with up-tempo basketball. Yet whether Wolves owner Glen Taylor is ready to spend on a coach with Nelson’s resume, especially after firing Rambis with two years left on his contract, remains to be seen.”
