All the critics cracking jokes about the Lakers' free agent signings will have to eat their words -- so says NBA champ Matt Barnes ... who tells TMZ Sports L.A.'s older roster is actually a GOOD thing!!!
It's no secret -- the Lake Show didn't get any younger this off-season ... adding guys like Russell Westbrook (32), Dwight Howard (35), Carmelo Anthony (37), Trevor Ariza (36), Wayne Ellington (33) and more joining forces with LeBron James (36) and Anthony Davis (28).
