91 DRTG over the five games without Ja (#1 defense in the league, by a considerable margin)The Grizzlies offense is looking amazing; they're all playmaking for one another. I guess the blessing they can take out of Ja's injury is they can learn to step up whilst he's out, and be better for it when he does return.
116 DRTG over the previous games with Ja (#30 defense in the league, again, by a considerable margin).
They went from being the worst defensive team in the league with Ja, to the best, without him. Whatever they've got going on now, they've gottta bottle it up for when he returns. GS, Phoenix and Utah have the top-3 seeds locked up, so that fourth spot is gonna be up for grabs.
