Managers can create all the lists they want, but when the time comes, it's about those who want to take them. We'll never know if anyone decided against taking a penalty; there's not a manager out there who would not 100% back that player and their decision.
I did feel that Poland had been practicing penalties and that we maybe hadn't. Whether it makes any difference, who knows?
In any case, anyone can miss a penalty. Even Kenny Miller.
