The Grizzlies are the team that can perform in the top three in the West, so the Grizzlies don't seem to have the need to push for a blockbuster trade before the trade deadline. But in fact, if the Grizzlies want to build a more competitive lineup around Morant at this stage, they need to make a move.
The advice given by the US media Jack Simeone is that the Grizzlies can promote trades with the Blazers:
The Grizzlies got: CJ McCollum, Cody Zeller
Blazers get: Steven Adams, Kyle Anderson, Brandon Clark, Zaire Williams, 2024 first-round picks, 2023 second-round picks (from the Lakers)
The Blazers sent CJ McCollum to the Grizzlies in a deal in exchange for some capable players and future assets, a deal that would prepare the Blazers for both sides, either building a lineup around Lillard or entering the rebuilding phase at this stage.
So far this season, CJ McCollum has averaged 20.6 points, 4.2 rebounds and 4.5 assists per game, in addition to 43.5% shooting and 40.5% three-point shooting. Such a scorer could have helped the team around Morant, and might even have made the Grizzlies a better competitive team.
As for the Blazers, getting players like Adams, Anderson, Clark and Williams will also give the team better lineup depth, plus the next two draft picks, which is still a very good chip reward.
There has been a lot of news in the past that the Blazers may break up the backcourt double-gun pair, especially when Lillard has made it clear that he wants the team to have better competitiveness, and there is not much time left for the Blazers. Of course, it is still difficult for both parties to promote such a blockbuster deal.
