Actually Muss's defensive scheme is good at holding down old ladies' bridge clubs, not actual NBA teams. The real ones shred it. We are defensive fakers right now. We run around, overplay everything, gamble for steals, double team...but can't stop a one flippered manatee one on one or in the interior. Hence teams with organized offenses that make the extra pasa see right through the light show and carve us up because we are constantly out of position and overmatched.
But there is a question, and hence a hope, if Muss would need to use the same gambling doubling scheme if he had real personnel on the interior. If we had a big defensive frontline rather than midgets, maybe we don't have to double, maybe we can discourage penetration, maybe we can protect the rim if the guy going for the steal comes up short.
In any case, Muss's defense isn't anymore effective than the one Rick used. Statistically it is in fact worse. It just looks better. But I'm holding out hope that if Saint Geoff can be persuaded to put down the "Midget Ball for Dummies" book he's been reading, and goes out and gets us something, ANYTHING, inside, that maybe we'll become more legit.
