The 2010 NBA champion talked all things Purple & Gold after leaving Craig's in L.A. this week ... and when he was asked about 'Sheed joining the bench, Metta says the move could pay huge dividends for the Lake Show.
"I think Rasheed is brilliant, smart," Sandiford-Artest said ... adding Wallace is "as good as it's going to come when you talk about a basketball brain."
'Sheed joins the Lakers with previous coaching experience -- in 2013, he was a member of the Detroit Pistons coaching staff ... and last year, he was a member of the Memphis Tigers coaching staff under Penny Hardaway.
Wallace, who played for 6 different teams over his 18-year career, earned a reputation for being a savvy player on the court ... something Metta can attest to due to their battles over the years.
Sandiford-Artest admittedly said he won't be keeping up with the Lakers' offseason moves -- like whether they will try to get Zach LaVine -- but come October, he'll be tuned in to see what 'Sheed and newly hired head coach Darvin Ham do with the team.
Speaking of the team ... Metta said he's not bailing on the Russell Westbrook experiment in L.A. just yet ... amid pleas for the superstar point guard to be shipped out of town.
"Westbrook is great. I just think Westbrook had a bad year," Metta said. "He's working out the kinks. I think he's going to be fine. I really do believe he has a big year. For sure."
