The Rondo of 2008 was a young man, a rookie who could be somewhat shaped and directed. He was on a team with 3 legendary players, heading for a championship. IMO he was much more open to coaching at that time. He bent to the play of these 3 much more experienced players.
As time went on and the big 3 began to age, and Danny handed the keys to the team to Rondo, "It's his team now" said Danny. From that point on Rondo turned into a director, and not a player. His style of basketball is overly controlling, slow and dated.
After signing with the Bulls Rondo stated "a lot of these guys have never played with a point guard like me."
He was correct, and they don't like it.
