The most dramatic zone Wooden used at UCLA was that 2 -- 3 half court press zone. It was designed, not to disrupt the opponent's offense, but to steal the ball or cause a turnover every time. And it worked magic for them.
The key man is the middle guy in the "3" -- he has to be smart, willing to take risks, anticipate, and either steal the ball himself or double team to force a bad pass so another player intercepts. At Springs Valley we ran this under Jim Jones with Charlie Carnes as our middle "3"guy; Lafayette Jeff ran something like this several years ago. A lot of teams struggled to even get the ball across the line, with turnover after turnover.
Could Brown or Smith be ISU's middle "3" ? ? ?
