Avoid: Making a move just to make a move
When it comes to the trade deadline and upgrading a roster, many fans believe their team should be making some kind of move just to be doing something. In their eyes, showing that you want to improve and making an effort to get ahead of your opponents is all that matters.
In reality, this could not be further from the truth. Obviously acquiring more talent can help in the long run, but it can also be detrimental to the team's success if not done in a calculated way with a very clear end goal in mind.
This is especially true for the Memphis Grizzlies' current situation. The team is clearly not in a position to make a run in the playoffs this season, so any roster additions would have to be ones that make sense for next season when Ja Morant and everyone else on the roster is back to full health and available to play.
Making a big trade to try to upgrade the current roster for this season alone would be like slapping a band aid on a bullet wound. If no realistic options are out there, the Grizzlies are much better off waiting until they are healthy and seeing what they have next season.
