I don't think Cooper Flagg will be included in any trade. When was the last time a number 1 draft pick was traded to another team before even playing a single game? Especially someone this hyped? Then again, with the Mavericks, you can never rule anything out.

It's understandable that LeBron would want to join a stronger team for one last try for a championship. This could very well be his final season. The Lakers just don't have enough depth. Even if they make the play-offs, it'll probably end in an early exit.
The last time that happened was Andrew Wiggins who got traded for Kevin Love because he was a better fit with LeBron James. Pretty similar situation to now to be honest. Cooper Flagg isn’t established. He could be a bust. LeBron is something special… I bet they also get a ton of picks. I don’t think a deal happens without Cooper Flagg. Dallas doesn’t have anything else to trade other than Klay.
