Post subject:  Basic player value calculations

So lately I've done some research to try and find how to calculate projected WAR based off of MLBPP abilities, and I've done pretty well. Here's what I have found:

Bat: use my CON/AVG chart to get contact, then find OBP by adding 60 points to the players average. Then use a basic calculation to find ISO based on MLBPP power ability: (Pwr + 20)/1000 = ISO.
ISO + AVG = SLG%. Calculate OPS+ (its fairly easy). A 100 OPS+ is an average score, for every point above or below average it is plus or minus 1 run, respectively.

Fld: 8 fielding = 0 runs above average, +/-2 for each incremental variation (...7 = -2, 8= 0, 9 = +2...)
8 arm strength = 0 runs above average, +/-1 for each incremental variation (...7 = -1, 8 = 0, 9 = +1...)
Eres does not make enough of a difference to matter due to everyone being so close

Bsr: 8 run speed = 0 Bsr runs above average, +/-1 for each incremental variation (...7 = -1, 8 = 0, 9 = +1...)

Rep: Add 20 runs for replacement level, it's hard to explain, but it's necessary.



After all this, divide total runs by 10, and you have your WAR! Here's an example player: 2/8/100/8/8/8/8.

Bat: 0 runs, .260 avg and .120 ISO equals a .260/.320/.380 slash line, which comes out to an exactly average 100 OPS+.

Fld: 0 runs, 8 Fld and Arm = average.

Bsr: 0 runs, 8 Spd = 0 runs above average.

Rep: 20 runs.

WAR: 2.0, which is exactly average. The player here has exactly average abilities, so I know these calculations work. These can help for reverse engineering players for success mode.



PS: This is not taking blue and red abilities into account.

PPS: Thoughts/Suggestions?

My thoughts...

Too advanced, I have no idea how you figure this.

It'll help for season mode to make the best team at the lowest price, kinda like moneyball

Hmmm.... Sounds interesting. How did you figure it out?

+1

This seems so needlessly complicated

I *kinda* understand this. I'll have to dig through Fangraphs a lot to figure stuff out, but my head was spinning a bit looking at all the info.

The main reason this would be used is to make sure we don't overvalue or undervalue real-life success mode players

Whoa this could really be helpful in my new log...

If you do use any of this, remember that, as Billy Beane once said: "My s*** doesn't work in the playoffs". Using this strategy I have been able to pretty consistently get to the playoffs with a sub-70000 payroll team, but rarely advance too far.
