Bottom line, when you look at the hard data for success, the numbers do not indicate "most successful". You can only reach that conclusion by introducing bias. Last I looked introducing bias was frowned upon by the scientific community.Again, these are your metrics. Not everyone has the same metrics. It depends on the question and what the answer will be used for. See my perfect tree example.
Also, you present these without context.
W/L -- 68% is good enough for about 20th among active coaches (about equal to Harbaugh) and includes a covid year and 2 years impacted by sanctions (note: I compared against active winning percentages not just specifically from the time CJF has been at PSU, but the point is the same)
Division -- only 5 coaches have won the division title (he being one of them) in that time period and two of them (Day/Meyer) were from the same school.
Conference -- See above. Two of the coaches who did win the conference are no longer coaching. So another way to say this is that he is only 1 of 3 of his active colleagues to win the conference championship. But that doesn't fit your narrative, so you ignore that point.
Playoff/Playoff Win/NC -- see argument above as to why this is also a horrible metric to use.
(and regarding my knowledge of the scientific method, please let's not go down the CV rabbit hole again. I assure you I work with the scientific method more (or at the very least as much) than you do. It's literally my job.)
Don't really understand your closing comments. I've never discussed CV with you and don't care to. I do find it quite an assumption on your part to make the claims you do when you have no idea as to the extent of my abilities or lack thereof. Doesn't seem very analytical.
