One concern GForce(it's Brewster from the ClubHouse):
If you're using three year averages, doesn't that negaye the fact that some young players are improving?
Tony Blanco, for instance, had a huge first year then was hurt last year and looks to rebound. To your formulas allow for slightly more growth of talent as opposed to a 34 year old major leaguer whose averages would be a little more accurate?
Regardless, if you do make a roster, I'll download it, and play with it myself
