So, we have Blatt and Lue. My five other assistant candidates at this point would be:
Alex Jansen (Jazz asst., coaches Canton Charge to 2 playoff appearances in 2 years. Good coach, relates to players, has a fast tempo and is good defensively).
Bernie Bickerstaff (current Cavs asst., former head coach who can help Blatt transition. Also good for continuity purposes.)
Nate McMillan (just under 1000 career games coached and had a .516% career win percentage, which is pretty good. Slow pace, but that won't be an issue considering he won't be in charge of anything. Good mentor to Blatt and players. Also is an assistant on the Team USA men's basketball team.). Another option here is Scott Skiles.
Anthony Parker (current scout for the Magic and finished career w/ Cavs. Parker played for Blatt and also played with some of our current players (Kyrie, Tristan, Andy, and Gee [though hopefully not for long]. Great option here because those players respected and loved him so much and with Parker there setting an example, our players will buy into Blatt's system.)
Make Price (beloved Cavs player who fans would love to see back in any role. Could help solve some of the problems in the backcourt and could also be a shooting coach. Has experience coaching throughout the league.)
I'd personally love to see all 5 of em here next year. So excited.
