I think you prove my point. The coaches made the changes as necessary. They are responsible and the get paid for it. Being armchair coaches is easy, we are always right and develop hypotheticals to prove our point, yet, the reality is that we do not get paid for it and HCDB and staff do. They see the kids day in and day out and see what is going on. They are privy to information that cannot legally be released to us unless the kid wants it out there. The have information regarding opponents that we do not have, analysis that we do not have, the list goes on.
To your point specifically, I stated previously that the level of analysis must be identical between the two (different words, same point). Thus, I agree, if you want to take one set of stats, you must include all like stats in the equation for both (or all in cases like DBs and WRs) when making decisions.
Once again, DeVito may be the right choice to start, I have only been stating that knee jerk reactions (emotions) are not a sound basis for making changes. I love the win. However, I think there is more to EDs tale of two halves. (But that is a different thread)
