Diego Maradona was a Gregg Berhalter level head coach and worse than Gregg as a roster manager.
He was a Top 5 all-time player, with many in their late 50s to early 70s thinking that he was the best ever.
In 2010, Argentina had one of the top scorers, if not the top scorer in the EPL, Serie A, and La Liga, they had the captain of the Champions League winning team (Inter Milan) along with its starts DM, and its leading scorer- who had both goals in the CL Final.
1) They barely qualified for the World Cup on a goal that would have been overturned by VAR.
2) They got knocked out 4-0 by Germany in the quarters.
3) The Inter captain along with its starting DM weren’t picked for the squad, Inter’s starting striker barely played, Carlos Tevez was allowed to play like a bitch and not pass to Messi due to jealousy… beyond frustrating.
You slap 2020-2024 Scaloni, a player who made the 2006 WC squad, but I don’t think he played, as the manager and they likely win the World Cup.
Good Managers are problem solvers and/or ego managers.
Henry & Vieira have shown to suck at this, but get repeated opportunities due to their records as players.
Gregg appears to understand that you should learn from people who have been successful, but he can’t understand how to apply the information he has access to.
Zidane was a deep lying playmaker who read the game as a player and would adapt when needed. He was also a generational talent with size, a violent streak, and a chip on his shoulder.
My guess is that he could manage the Real Madrid locker room egos because he was always good at reading the entire situation and that he could physically destroy anyone who challenged him.
Ancelotti was a good player, I think (never have seen anything about his play), but has been excellent and mediocre as a manager.
Great players rarely make great managers, but they are given many more opportunities than all other managers combined.
