Just by going back to 2010 looking at top 3 finishers:
Ice Box jumped up 4,5 points when winning FL Derby, regressed just a point when getting 2nd in the derby after a really messy trip
Paddy O\'Prado in the same year got 3rd in the derby, jumped big 2nd race out as a 3yo, just kept going forward from there.
Animal Kingdom has been mentioned already.
Nehro in that same year made sudden huge progress and just went forward in every race from there. Hope you didn\'t \"learn\" too much from that huge bounce.
I\'ll have another. Built upon his great 2yo foundation (9 8 19) to win both preps and the KD as a 3 yo, running only good numbers (1 3 1).
Dullahan, got 3rd in the derby, jumped 3,5 points at first and then 3 points more in the next start. Went forward in the Derby, too.
Orb. Jumped 6,5 points. Sheets looks a lot like Always Dreaming up to this point. Then he jumped 3 more points in the Florida Derby to a big negative number, a number he paired up in KD. If AD goes on to win both Derby and Preakness even doubters will have to say their sheets are as identical as one could ever find.
Not top 3 in the Derby, but Pletcher\'s Palace Malice jumped 4,5 points that same year to win the Belmont in good style. Haven\'t seen his sheet as a 4yo but pretty sure that one turned out pretty good.
California Chrome. Had established oneself as a pretty mediocre 2yo (6 starts, only one of those were single digits). Then goes forward 11,5 points to a 6,5 points new top. And stayed there.
Danza. Went forward 5 points to a 4 points new top. Stayed there and got 3rd in the derby in spite of a terrible trip (Pletcher).
Wicked Strong that same year got 4th in the derby, jumped 8 points to win the wood running a neg 1. Ran a 1 in the Derby with a difficult trip. Even paired that 1 in the Belmont.
2015 was a great year for sheet theorists. Too bad \"none\" of you cashed by getting greedy
2016 was another good year for sheet theorists. Didn\'t look like you cashed this year either.
BTW: not saying you couldn\'t have liked any of those mentioned, just pointing out the big new tops leading up to their triple crown races.
