If you think a coach is going to walk into ESA and set up a system in year one then you're setting yourself up for disappointment. Next year will likely be a step back as far as schemes and complexity goes.
There's a big myth here that Steve Clifford has found a way to hide Al Jefferson in his defensive schemes (so much hate and vitriol will lead to crazy *** notions like this). If you read Clifford's interviews you'll see how asinine this suggestion is, right from the horse's mouth. Clifford, like every good coach, has installed a base NBA defense and relies on his on-ball defenders to limit the amount of double teams they have to use. He has stated several times that he could do more stuff, but his team isn't ready for more complex rotations. There success is all credited to MKG's elite defense, and solid ball stoppers elsewhere.
Those expecting a new coach to bring success are going to have another miserable season on their hands.
