1. At some level, it doesn't matter whether you play horizontal stack, German, all-upside-down, or lefty lifts. If you make good passes, you'll score, and if you make bad passes, you'll turn it. All that the system does is to create more or fewer opportunities to make good or bad passes. Leaders are responsible for the system, players are responsible for execution.
2. If two teams are equal in talent, it's the team that makes the plays that will win. Sometimes those plays are just willing yourself to be open at stall 8, or selling a decoy cut to free up a long cut.
3. But more often, those plays are picking up your teammates when they make a sub-optimal play. This doesn't mean that you make hero throws or cut when you're not supposed to, but that you play heads up and balls out.
4. If you throw a pass that's incomplete, it's your fault. If a pass that is thrown to you is incomplete, it's your fault. If you're on the field and your teammate throws a high stall pass that's incomplete, it's your fault. If you're idle on the sidelines and a pass is incomplete because you could have seen something that might have made a difference, it's your fault. Because of all my talk over the years about root causes and team errors and "what's wrong with right here", I am probably most at fault for this attitude being part of the culture. But just make the play and shut up. The way it should have worked was that instead of blaming the guy at the sharp end, everyone involved should have realized that they contributed to the error. It shouldn't be, "Hey, the pass wasn't right at my gut, sorry I couldn't save you."
