I agree with that mostly (say 98%).
The one outlier, which I've seen happened to other players on game day, is that they completely misjudge the traffic. The patterns have fluctuated wildly in the last couple years. Some days I can get to the stadium with zero issue, and other days it's a complete nightmare.
Granted I don't know what time they are expected to report, but even so much as a 10-minute swing in your departure time can result in a 30 to 40 minute delay.
