How are values calculated?
For rotisserie, values are calculated using z-scores, a common statistical technique for comparing things that from different scales.
For points leagues, z-scores aren't needed; it's just each player's total amount of points.
In either system, each player's total is adjusted so that the last draftworthy player at their position is worth 0.
You can read more about calculating values at How to value players for fantasy.
My league has a snake-draft. Why do I need dollar values?
Feel free to ignore the specific dollar amounts if your league doesn't have an auction. All you need is the player sequence that Projectile provides you.
No matter the league settings, I find the $1 baseline from the values to be useful for recognizing the distinction between "starting caliber" and bench or waiver wire players.
What are the default league settings?
This is the "traditional" 5x5 rotisserie setting with CI and MI. 12 teams.
C, C, 1B, 2B, 3B, SS, OF, OF, OF, OF, OF, CI, MI, Util, 6 SP, 3 RP
Leagues may use 9 P rather than a SP/RP distinction, but assigning a certain number of SP will keep things in line with the market.
Yahoo's standard is 12-team, 5x5 rotisserie league with slightly smaller rosters:
C, 1B, 2B, 3B, SS, OF, OF, OF, Util, Util, 5 SP, 3 RP
Note that Yahoo Public leagues actually allow 2 SP, 2 RP, and 4 P. However, with an IP minimum, I find that assigning 3 of those at-large slots to SP improves accuracy.
ESPN uses full size rosters, but with only 10 teams per league. Their point system downgrades speed in favor or patient power hitters. (Although watch out for strikeouts.)
Hitting: R: 1, RBI: 1, TB: 1, BB: 1, SO: -1, SB: 1
Pitching: IP: 3, H: -1, ER: -2, BB: -1, SO: 1, W: 5, L: -5, SV: 5
C, C, 1B, 2B, 3B, SS, OF, OF, OF, OF, OF, CI, MI, Util, 9 P
(Notice that with points, it's not necessary to force P into SP or RP.)
What goes into the projections?
Most of the projection creators are tight-lipped about what goes in to their systems. The exception is my own Open Projections, which are open source and fully documented.
There are a few special combinations used on Projectile:
- What shows up as The BAT is really The BAT X for hitters and The BAT for pitchers.
- The playing time adjustment is an average of the PA/IP from FanGraphs' Depth Chart projections and from ATC. Systems may end up with slight differences in PA due to stats missing from the FanGraphs projection pages (SF and SH).
- The Aggregate projection is a simple average of all of the projections. (The playing time adjustment is applied first, so that each system is applied equally.)
