I can see Rondo as a head coach with no experience taking over a veteran team that’s trying to win before their window closes. He could keep the stars in line, draw up ATO plays, and jump on the refs when they need it. He would have assistants handling the rest.
The Celtics are not that team yet. They’re still young and need a coach that can develop their games and lead them past frustration. Rondo might be a good off court strategist, but I think he needs to spend time as an assistant before he’s able to lead a team with developing superstars that still need a coach that can get them to their ceilings. Someone that’s - been there, done that - but can still teach. I don’t remember Rondo teaching, he’s more - do it my way.
Sam or Chauncey sound like good choices to me. Juwan too, but I doubt he’s ready to leave Michigan until he wins an NCAA title, as another poster mentioned.
