The NBA playoffs are no joke -- and NBA wives need to do WHATEVER THEY CAN to keep their men happy ... from private stripping to foot rubs ... so says "Basketball Wives" star Jackie Christie.
Jackie has some experience -- she's married to ex-NBA star Doug Christie, who played 15 seasons in the league.
Christie says when the playoffs come around ... NBA wives need to switch into "support system" mode -- "Let him watch ESPN, be their wife, their secretary, their dancer, their stripper ... whatever you need to be to make him comfortable."
Jackie says she doesn't just talk the talk, she walked the walk when her hubby was still playing -- "I'd rub his feet, I ran his bath, cook his dinner, I kept his house quiet. I ran it like a military base."
