The roster's have never been too brilliant. In the late 80s/early 90s they were pretty awful, particularly as regards secondary, backcourt, playmaking and guys with range.
When Utah was built around these concepts, or provided them, the team became an immediate, and obvious contender. Enter Hornacek.
Still, I would agree that, for instance, Sloan did Utah no favors with his rigid nature against a team like Phoenix in 1990. You watch that fifth game, Utah's ahead.
But how? By running. Sloan didn't want that. He stopped that. And Utah stalled in the fourth, losing by a couple points.
The other interesting note from that game is superstar power through facilitation. Thurl Bailey scores quite a few baskets in the fourth, probably more than Malone and Stockton, but everything he gets comes off of their presence and creation.
Sloan's system can do a lot, but it can't do what star players, plural, could within it.
Watching that tape, I question Sloan. But I also question, just as it was to be against Portland, where the rest of the roster talent is on offense. No range. No spacing.
In that sense, Layden's more uptempo style was superior for such a flawed team.
