Shaq marked the end of the Suns team that BC put together, so having him in the comparison throws the whole thing off. To me - I find the emphasis on defense to be extremely different over what happened in Phoenix. And the difference would probably point to the relationships with two different coaches.
And before anybody questions the Raptors' emphasis on defense - listen to what has been said in the off-season so far, look at the improvement over the last two seasons, check out the kinds of players that have been acquired, and wait for the season to start. JO is the missing piece to more of a defensive masterpiece than any kind of Suns east kind of team.
