If you put current day LeBron James on your states worse high school team... do they win the state championship?
To figure out that answer, ask yourself this first: If you put current Saitama with C class, are they stronger now than S class ?
Assuming he’s building chemistry with the team all year long, they win easily. If he’s stepping onto the court with them for the first time on the first day of the playoffs, they still most likely win.
No. Lebron has too much prestige, and rejects playing, thus becoming LeCoach to a team full of unathletic white kids to preserve his ego.
