The book is still out on Mike Brown. You don't just win 60+ games with that Cavs roster. I think its pretty clear that players from the Lakers that we thought were high caliber turned out to either regress horribly (Nash), or were injured or under utilized ( Pau, Dwight).
It's hard to argue that Phil Jackson himself would have changed anything, considering his team that was two years younger got swept by Dallas. The roster just wasn't anywhere near as good as it looked on paper for a number of reasons.
Brown has a chance to show how good he really is with this Cavs team. He'll get the opportunity to coach up a rebuilding team and have to make rotation decisions that aren't obvious due to the variety of young guys they have.
My Coach tiers:
1. Pop, Thibs
2. Doc, Monty, Carlisle, Adelman, SVG, JVG
3. Woodson, Karl, Vogel, Gentry
4. Spo, Brown
5. A bunch of other guys - Wittman, Corbin, Del Negro, Jackson, etc
6. Stank Trash Tier : McHale, Mike D'Antoni, Dwayne Casey
