Ok. Improvement and Regression in Top 5 - 10 - 20 in 2024 that should help you to understand ....a lot has to play out and even a 2 or 3 loss team has a shot at winning it all!!
Case in point for 2024 / might dip into Top 10 of 2023 too:
Rank improvement in offense/defense from pre-season poll to final Jan. 2025 SP+ rating
PRE-SEASON Rank:
1. Georgia > regressed on their SP+ numbers by 11 rank places at the end
2. Ohio St > improved SP+ greatly and won easily!!!
3. Oregon > SP+ totals for Off/Def added to same number by the end of the year
4. Alabama > improved final SP+ ratings by 1 rank
5. Texas > lost to Ohio St. and in my opinion, bullied/controlled and now they are #1 not letting their star backup with multi-offensive tools like an extra backer to play and to get back into it, now the coaches and AP make them #1 with this QB???
-improved SP+ rank by 1
6. Penn St. > had a final game berth in their hands and the Irish snatched it away in an epic game
-improved SP+ rank by 15 by the end ...many top stars back and ol-ine and get strong transfers/freshmen but only #2 preseason which should fire them up!!
7. Michigan
> regressed by 60 ranks
8. Ole Miss > improved by 12 ranks on both sides of the ball in total
9. Notre Dame > in the final
-improved SP+ ranks in total by 8 ranks
10. LSU > regressed by 5 total ranks
15. Tenn. >moved up to #9 and improved by 5 rank pts
19. Miami > moved up to #10 by end and regressed by 3 rank pts

I think consistency is key... but so is improvement if you wish to rise through that Top 4.....there are no longer any super powerhouses as there might have been before
This makes it great for bettors....and with a little elbow grease...one might be able to find the pathway to make a lot near the end of the season and through the playoffs..
Then there are guys like the 'Smoking Cat '...my friend and someone I look up to ....who find those nuggets rated 110th - 35th rank that rise up and roll.......INDIANA and ARMY come to mind the nuggets he found and pounded the table....Texas St as well...Tulane .....what a season Wahoo had 
and I commend the methodology he uses (a secret!!) haha but I see it in the big SP+ changes which is another reason why this week I am plotting or inputting the whole 2024 season to see what transpired in the data
Put in the work DURING the season and watch for improvement to find those teams rising in SP+ playing a team that is rated higher but inconsistent or a weaker team that is inconsistent and I think you go with it!!!
Proving is hard. Talk is easy.
