The Lakers, league sources say, have not ruled out simply parting ways with Westbrook via the waive-and-stretch provision. A straight release of Westbrook that essentially transforms his mammoth player option for next season into what lives on their books as a three-year deal in the $15 million range annually would move the Lakers out of luxury-tax territory and make it far easier for them to retain free agent-to-be Malik Monk, who at times has unexpectedly appeared to be the Lakers’ most dependable player not named LeBron James throughout a nightmarish 31-48 campaign. Facilitating Monk’s return might be reason enough for the Lakers to go this route and is expected, league sources say, to be under consideration.
