I played for the same Tom Kimbrough, just a few years after you. I know all about the Plano teams, Needham lived a few houses from me. Kimbrough and Brence are the reason Im in coaching, If you still live in the area, lets meet up and talk about coaching philosophies since you have so much knowledge.
You're the coach, not me. Yet I'm not the one talking about using a perennial backup WR at RB based off one play against Kansas in a blowout and a 4 year old tape against a perennial backup DB. The McCullough brothers are coaches as well, and how are they doing? Each week one has to wonder how bad they will get beat. One of them wins this week, since the two pair off in the season finale...
If you know all about Plano football, then you know execution trumps potential/ability 85 to 90% of the time. Kimbrough was a genius at having game plans and schemes that his team's could execute. If you didn't execute in practice, then you didn't see the field. If things were too complicated, like they were against Duncanville and Richardson in '86, he simplified it.
It is rather simple. If the plan isn't or can't be executed by those expected to do such, it will rarely work. There are exceptions, but we aren't talking about boxing. Teams delivering knockout punches are just that, a TEAM. I've posted my defensive philosophy on other threads. They aren't hard to find.
I'm not in the area. I live between the whorns and the rapists off of I-35. And as for your other comment... I am in this video, but does that really matter? Do you think that a guy on the bench doesn't know what to do? Why did we use 8 RB's in the game? Did we need that many? And why is LaMarque the only one to have the video? I suppose that doesn't matter either...
