I believe a coaching system where there was a head coach of offence and a head coach of defence could work out if the coaches could work together.
Brown and Dantoni could be a strong combo if paired up and they meshed.
it's not that mike brown doesn't know offense or D'antoni doesn't know defense, it's just what they choose to emphasize.
MB's philosophy is that a team can't contend unless they learn how to defend at a high level, and that NBA players are too good and difficult to stop, thus the entire team needs to be focused on stopping the ball.
The issue with that is a bunch of 22 year olds don't want to have an entire year or two of practice devoted to learning defensive schemes. They get sick of it and don't try.
MB ran a variation of the princeton offense, same as Byron and the same as Blatt, IMO the issue wasn't with his plan, it was the fact that every ball handler that cavs had (Kyrie, Jack, and Dion) are all truly score first guards that aren't adept at running offenses.
