Calculating Ratings


Camby

Recommended Posts

I'm using Dylan Bradbury's ratings calculators (which are awesome) to update my rosters for 2011, and was wondering if there is a community-accepted approach as to what stat totals to use, i.e., latest season, whole career, or an average of last few seasons. I guess I could just alternatively ask: What did kgbaseball do with his rosters? Lacking an established paradigm, I'd love to hear some suggestions from the community on which direction to proceed. Thanks!

Thanks for the kind words about my calculators, Camby!

Most people I know, regardless of the game played, use the three year averages. That's fine for established players, but it bugs me if you have a star that has an off year, and it brings his totals down.

Or a guy has 3 years played, and isn't named Albert Pujols (meaning they have a bad rookie year, which Pujols did not), and then blossoms into a star his second, and third year. Even though the guys is now a big time star, his bad rookie numbers kill his ratings.

Maybe Dylan could develop his generators to calculate based on career totals/averages! :spiteful:

They already are! The pitching and defensive calculators do this automatically, and the batting calculator asks for how many seasons of data the stats contain.

I do them on my own, its part of the fun.

I look at the leaders in BA and SLG (r/l splits) and determine what's a 100 rating, and make the 'floor' a low number, but around a 40 rating, so a bad major leaguer is still decent compared to the AAA guys.

Yeah, I'm also encountering this problem using the three-year-average. Another sticking point I have is trying to figure out what to do with the young kids who are just breaking into the bigs and don't even have a full season under their belts. Using either their minor league or major league stats in the calculators don't produce ratings which accurately reflect their ability.

I'm thinking using the three-year-average method combined with some subjective but judicious user-tweeking is probably the best approach.

I don't know if this is useful to you guys but there are certain penalties enacted in my calculators if a batter doesn't obtain enough ABs per season.

Penalty as in that season counts less, or penalty as in they take a hit to stats?

Penalty as in their ratings are penalized.

This is all hypothetical but say two players have the exact same stats, except one of them played in all 162 games and the other played in fifty.

The player that played in fifty games, his ratings will be penalized.

Hope that makes sense.

That does make sense to me. I'm glad I know about it though, as I might edit it a bit in some exceptions. I don't know how your weights work, but if somebody had a down year due to injury I don't want them to double count it, or if a player was injured but healed well. Though I'm having a hard time thinking of specific players at the moment so I should probably stop talking.
