I feel you. AJJ, A-Jax, Dairy Bird (or Pale Ellis - depends on your flavor). That is how I try to use their naming to keep it straight. One thing appears certain early: AJJ absolutely has the innate ability to become a meaningful NBA player. He is wildly inconsistent because he is so young and inexperienced. However, he has an incredible handle; change of pace; effort; and size. He can take any NBA player off the dribble and bounce right now. His shooting is extremely erratic - game-to-game he can go either way. His FT appears a work in progress (which for a PG is problematic if it doesn't improve). Either way, it's a meaningful LT draft pick that could work out akin to Anfernee Simons (AJJ is already a better defensive player) or Dejounte Murray. I like the player and the potential here.
Also, I highly advise avoiding these pre-season games. With a passion. The Bucks depth is absolutely non-existent outside the top 8-to-9 players. IF AJJ improves and becomes more consistent and AJ Green continues to play solidly within the rotation (unknown - his shot looks funkier this pre-season and that is mildly concerning) we might have 10-11 playable NBA players. At this juncture, Tyler Smith; Marjon; and A-Jax are all G-League players from my POV. I personally don't see Marjon ever becoming anything in the NBA - that ship has sailed for me. I've never seen a more athletic guy than A-Jax entirely incapable of getting to and finishing at the rim. His shooting concerns would be a non-factor if he could get to the rim. He continues to avoid it like the plague - a true wonder. I like Chris Livingston. I still think he's a couple years of growth removed from being an actual NBA rotational player. He has the try hard. He has the size. He has some intangibles. However, I just don't see him getting rotation minutes. Anywho, the pre-season second unit is akin to their Summer League squads: ugly and depressing. 😅
I will also quickly say: Anthony Johnson Jr. (let's go full name here!) is likely getting consistent minutes this season. The Bucks 8-through-10 players are not good enough to keep him out of the rotation. I think he gets run and he gets run early and they build it up as the season moves along. Obviously not a one-and-one comparison due to talent and pedigree, but it's important to remember Doc has SGA his rookie year with Chris Paul on the roster. SGA played consistently and was a key rotation piece.
