I'm not directing this at you as this more rhetorical but...a chart? What's wrong with a coaches gut and intuition? Charts...schmarts. Oh my. At least I'd bet PJ didn't need a chart in that situation.
It’s part of the weekly gameplan. Well, it usually is. The matrix of time, score, yardage, etc. is wrapped into the game planning for the week. The chart they speak isn’t the one everyone is assuming where it tells you whether or not to go for two or not. It’s the matrix described above planned for during the week.
For instance, the decision for what to do against NIU that situation wouldn’t necessarily be the one you plan for against Clemson given all of those same variables.
What happened is akin to a military commander planning it all out with his war council and then in the heat of battle waffles back and forth and can’t make a decision. Collins is faking it until he makes. His actions in game management seems like he has no confidence in himself. The bluster is just cloaking it, as is usually the case with the loud ones in the room.
