One Monty play that I haven't seen with any of the coaches who succeeded him is the double-screen, where two players screen their defenders at one side of the key. The shooter passes the ball to a 4th teammate, and then he crosses the key behind the double screen, and curls around the edge of the screen, receives a pass and is wide open behind the wide screen for an easy 10-15 foot jump shot, either straight or sometimes off the glass, depending on the preference and skill of the shooter. Monty's teams seldom ran this play, but when they did, they ran it to perfection, with Allen Crabbe, Justin Cobbs, and Jorge Gutierrez as the shooter.
This is an old play from another era. We ran it as sophomores in high school in the 1950s, and we ran it often. This play takes at least 4 players in specific roles and duties, and timing was everything, to hamper defenders from switching and preventing the shot. I'm not sure players today are comfortable with this type of disciplined play, requiring teamwork of 4 or 5 players, and a lot of practice to get the timing right. Montgomery was a master. He'd run a play, and even if it was successful, you might not see it again for a few games. Just to make opponents aware that Cal could do this any time, and they needed to prepare for it. I remember a period where the offense was struggling, and Monty taught them a weave, an offense used back in the 1940s into the 1950s, which used to lull defenses (and fans) to sleep The weave uses a number of dribble handoffs, where the dribbler sets a screen for a teammate, just as he is handing the ball off to him, so he can't be called for setting a moving pick. It required learning a new skill, and it required practice to get the timing perfect. The weave often resulted in a wide open layup. Monty used the weave just a few times, but it was enough to get his team out of its funk and get his offense back on track. He never used the weave for the rest of the season. Just kept them guessing that maybe he would use it.
