"Trust but verify," said President Reagan. Former Patriots' consultant Ernie Adams broke out "Ernie Cards" each Friday in preparation for NFL game day. Some called Adams "Belichick's Belichick," a man with an encyclopedic football knowledge and memory. Challenging players is never optional.
As coaches, we put players in position to succeed by learning, teaching, and finding ways to seek technical, tactical, and psychological edges. Curiosity helps.
"Ernie Cards" posed situations to challenge players and help "get them on the same page." All of us have lost games because players made mental mistakes or got "brain lock" in critical situations.
Tailor to high school, college, or professional level. Here's a sample selection via ChatGPT Plus. Every coach will generate their preferred answers.

The Patriots had a relatively secretive process, so no images are available off the Internet. There's a legend about a phrase, "Pink Stripes," on Adams' white board. Adams said he would take that to his grave. It might mean laundry pickup or indictment of NFL officials. We'll never know.
Lagniappe. Measure it to improve it. "Objectives and key results were embedded in the management system at Intel, but they were also a philosophy, a seminal teaching system. We were all taught that if you measured it, things got better."- John Doerr, "Measure What Matters"
Lagniappe 2. Off-ball stagger for 3. Ryan Pannone always a great sharer.
Coach Brad Stevens ran this misdirection stagger screen action for a 3. Great action to use to attack the low man with a shooter as they are pulled in with the ball in the outer 3rd of the court. pic.twitter.com/WVwrUw3Lo5
