I guess the problem with this is, how much is it to do with what Pat created? It's not like Spo came in and started his own thing, he came in and continued something that was already established. And it must be taken into account that making the playoffs in the East is a considerably easier task than making it in the West.
He came into the league as a HC with a silver spoon in his mouth.
All those players that the Heat scouted/developed across his tenure have had very little to do with him.
