These are career to date impact estimates or to a certain year or peak?
Rookie season averages in these stats, by draft pick, 2013-2025

Yes.^^
I messed around with age adjustment and decided (again) not to bother.
Also "yes" for WShr, perW, and eWin.
Today's top-to-bottom spread is smallest yet! Down from 2.47 on Jan 9, to 1.91 now.
The whole field has improved since then, by an avg of .60 in MAE:
1.04 KPel
.89 DQin
.88 Crow
.80 Mgoo
.80 avgA
.73 WShr
.68 bpmW
.67 medi
.65 25pr
.63 dtka
.58 eWin
.47 Walr
.47 knar
.40 EExp
.40 bmgm
.37 Ebet
.24 perW
.16 DRKO
I do have detailed aging curves developed for BPM; next year we can include those.

I laid out a true BPM 2.0 projection system in this post:
viewtopic.php?p=37451#p37451
I just haven't gotten around to actually doing them ahead of the season.
I also have better priors now than those mentioned in that post

New leader is BetMGM, a 2nd gambling entity I added on Jan. 5 [What I had called Vegas is now Ebet].
Last year at this time, they were a distant last place, almost 3 off the lead.
This is the 7th entry to be on top since mid-Nov and 4th in the last 8 days.
