The other thing that happens, and that I think points to why Pat is so 'passive' on the sideline, is that a person who understands they have early symptoms becomes distrustful of their emotions and perceptions. In private settings (practice, home) a 'mistaken' reaction is OK because everyone understands and the fall-out can be managed, but in a public situation the fear of making a 'mistake' takes over and the compensation is to become passive or as Icebear says, to fall back on formulas.
So I think Pat's actions in practice may be much more commanding than on the sideline. In that public environment she may not trust herself.
