I don't really get how this is the agent's call. That is what is troubling for me. If the doctors clear him to play and deem him not at risk of future injuries, who is the agent to say "he won't let him." That really strikes me as getting off on the wrong foot with the team (honestly didn't intend the pun but i will leave it).
I also don't agree that this is good for the 76ers in any way. They clearly will not have embiid, okafor and Noel on their roster indefinitely. The beginning of this season could have been the only opportunity to see how Simmons played with Okafor versus how he played with Noel versus how he played with embiid. Maybe Simmon's playmaking makes Noel look like an average offensive players whereas Okafor clamps down the ball movement too much to fully utilize Simmons? Maybe it would be the other way around.
Now they have to make that decision without seeing those guys ever play together. That is a pretty tough break for them.
Fun food for thought: If it was known Simmons was going to have a broken foot and miss the entire season would he still have gone first? Would the 76ers have taken Dunn or Ingram in that case? Would we end up with him?
edit: as a basketball fan i also just wanted to see him play.
