I've gotten pretty into devy leagues over the past 5 years or so. The configurations in which I am a part range from x devy picks allowed for the entire league as a whole to x devy picks per team to a combination of those two things.
So I don't have the data to provide long-term analysis, but will share what I have seen. I am a long-time college football junkie, so I can speculate some as well (no representations as to the veracity of course).
In the leagues that have a cap for the entire league, the rebuilders take those spots very early. For example, a league I am in that allows 24 devy picks will usually see all of those claimed in the first 40 picks or so.
I guess I will find out more as time goes on but I put QBs up there with WRs and completely ignore RBs. I can see QBs having a higher bust rate, but I think the top-end value is through the roof, especially when they hit early like Caleb Williams (I should also specify that I exclusively play superflex, which obviously has massive impact).
My leagues are deep, so top incoming freshmen are scooped. The #1 devy frosh, Ohio St. WR Jeremiah Smith, has gone in the first round in nearly all of my drafts. Last year's QB class went really high, and while there wasn't a Williams that popped right out the gate, guys like Arch Manning, Nico Iamaleava and Jackson Arnold have a lot of value.
Value changes a lot throughout the season, and even in the pre-season with transfers and such. College football is wild right now.
Anyway, I love the devy aspect, and those are the only new leagues (not really "new" I have just been picking up orphans that need some TLC) I join nowadays. I love college football so much, and much prefer the roster-building devy stuff to playing college fantasy football because stats can be so wonky.
