I agree with your factors concerning the preseason rankings. Of the 3 factors, I believe Team talent is the most important of the 3. The Blue-Chip Ratio is a good indicator of the talent level. The Blue-Chip Ratio is simply the percentage of 4-star and 5-star players on the team versus the total number of recruits over the
last 4-year period. Below is the most recent list I could find which is for the 2021-22-23-24 recruiting cycles.
This list includes transfers. Below the list is an article by Bud Elliot who is the originator of the Blue-Chip ratio. It is worth reading. The list below is from this article. The author acknowledges the exceptions that do not live up to their team talent. But it is hard to ignore the correlation between the BCR and the teams that are in the Playoffs and in the preseason rankings. One quote below from the article concerning development of players.
"That is not to say that development does not matter. It certainly does. But nobody wins a national title by player development in lieu of elite recruiting. Plenty of coaches who are regarded as elite have never sniffed winning it all because they can't accumulate enough talent. On the other hand, there are examples of coaches who are not regarded as premier head men who have won it all thanks to elite recruits. Not to lump them into the same category, but nobody ever accused Gene Chizik, Les Miles, Mack Brown or Ed Orgeron of being tactical masterminds."
