I'd also prefer 2 years + an option year. After this season, I didn't think there would be any chance they'd let him go, he's a very average coach, I'd prefer another person, but if he takes them through the rebuild, then whatever, not a huge deal, the team is still a few years from winning anything and if the players like him, I'm good with it.
He's not a championship level coach though, doubt Masai believes it either.
Casey has improved as a coach. Is he a strong defensive coach yes. Did he have the personel to match up well with pierce and Johnson no. I don't think we can blame him for that. I was a bit surprised he never went back with fields, who was the only guy the whole series that had any semblance of success against him. Casey is stability, which this franchise needs. Multiple years in a row going to the playoffs. With young guys on their roster, one could realistically expect improvements still from Derozen and then huge upsides in Ross and Val. Lets be honest, raps nearly beat the nets with a struggling ross, an inconsistent Val and a hobbled Amir. Plus two bad matchups with JJ and Pierce.
Coach Casey needs to spend alot of team on end game situations. coming up with play designs that utilize the strengths of the players, but is not too predictable. Hiring an expert in this area, and/ or studying tape could go along way. If Masai can add a piece or two, a big. physical wing that can shut scorers down ie.tucker. I think Masai would have his defence set. Just needs to work on becoming a better offensive coach. Especially at the end of games.
