Lebron James with his 100th triple-double despite losing against the Grizzlies. Congratulations to him and is now listed on the top 5 of the franchise joining Jason Kidd, Magic, Robertson, and of course the top 1, his teammate, Russell Westbrook with 189 triple-doubles already. If he will have more years to play he might even pass Kidd at 4th place with 107 or better Magic @138.
I think he can surpass Kidd at fourth place in terms of triple-doubles. 7 triple doubles is still achievable knowing he is LeBron

They lost still to the Ja Morant-less Grizzlies and they won 4 of their last 5 games without him. It seems like they are playing better with Morant out didn't they? Hmmmmm. Anyway, their next game is against the Rockets who is on a 7 winning streak and they also defeated the Nets on their last game. Grizzlies or Rockets?

Nikola Jokic also registered another triple-double in 3 consecutive games. He is back on his MVP caliber type of game but it's not enough to give them a win. Someone in that Nuggets team needs to step up his game or they will be doomed trying to reach a playoff spot. They are now at 7th seed and it's not safe there.
The Nuggets don't have Murray and Michael Porter Jr. because of injuries.
Well, it seems like Jokic is having a hard time carrying the team himself and we can see how impactful Murray and Porter is with the team. I think the problem with the Nuggets right now is their bench. As I'm looking at their roster, it seems that they don't have any reliable bench player unlike other teams. Like you said, I think that somebody in the Nuggets needs to step up if they want to enter the playoffs and at a higher spot because 7th spot isn't a safe spot.
