I think one of the tactics that can beat the Look inside can also be Outside Isolation, for which almost no team have the right players. You can create the most mismatches on SG, SF and PF positions, so those three players should be "unique", but not in a way to create salary monsters. SG should have great IS and PF should have great JS and JR, but main "star" of the team should be a great great SF. PG and C should have supportive roles: OD, PA and DR for Point Guard and RB, ID and PA for Center. I guess a team like this could be near unbeatable, but still manageable in terms of salaries.
