It would be a jackpot for the Lakers if, in any case, Blazers will release Lillard for Westbrook
That's the perfect word for it. "Jackpot"
A variable I've seen discussed here a few times is the AD situation.
Unfortunately he is in a delicate situation and has regrettably spent more time off the court due to his injuries than playing.
But anyway, I believe for the Lakers to be champions in this season, they need to evolve a lot, not specifically improve their roster (this is an important factor), but something more relevant, is the chemistry between the players, which I saw a few times in some games the Lakers played in the previous NBA season.
It's difficult to create strong chemistry if they keep on rotating new players on their roster. It cannot even be compared with the likes of GSW, Phoenix Suns, and Grizzlies. There's a savior though, Lebron James. He had been a leader for a long time and he knew how to create chemistry in a short span of time. I remember him creating events for the Lakers players a lot of times to strengthen that chemistry so it will just depend on them if they want to join.
AD and Lebron won't have a problem and they kept Austin Reaves which I think will be a lot of help to them.
