What formula would I use to determine added positional value?

I prefer not to stick to formulas for rankings. Rankings will give you a great idea of what players may be worth (given position scarcity, etc.), but I prefer to refer to several mock drafts in order to get a sense of draft psychology.

Rankings are great for a blueprint for a draft strategy, but they'll never prepare you for the runs and gamesmanship that take place in the draft.

This seems to be useful if you want a quick ranking based on your league cats (uses ZiPS projections). Ultimately your drafting strategy will have to adapt in real time to what other owners are doing if you really want to be successful, but something like this (or other similar draft kits) are probably an easier way to get yourself ready for the draft than doing things manually (for those who don't have the time). You can modify the rankings (dollar values) depending on your secret sleeper, etc. afterwards. The system has position scarcity weighting built in if you want to use it (not sure how it's weighed though). But exporting the ranking to exel is only for subscribers, I think I can live without that :P

This cheat sheet compiler was really handy when I drafted last year. This year's version's not up yet.

I just did my own serious rankings for the first time.

I didn't do anything unheard of.

Basically did thing with stan dev and averages and z-scores

did that twice for each for....
once comparing him to his respective position
another time comparing him to the league

weighted some stats heavier than others (hr > sb)


i had trouble with ranking pitchers and have not even included closers in my rankings, but all in all I'm happy with what i have


I, like couple others have mentioned, usually need to no number of mock drafts to get idea of where players are going and how people are acting.

care to elaborate on your method involving z-scores? I'm messing around with different methods right now but I haven't tried that out yet. Also, did you use arbitrary weights for stats based on personal preferance or what?

The price tag is a little steep, but if anyone needs a good introduction to marginal value, regression, ect. with respect to fantasy baseball this book is very helpful:

There is a lot of Excel help for those unfamiliar with spreadsheets as well.
