I'll throw in an example of what I expect. I remember a 21-year old rookie whose OBP was only .012 above his BA in his first season -- 12 walks in a full season. Smart player, mediocre batting average with basically no power, the kind of a player who you'd think would really cultivate his batting eye to increase his value at the plate.
In subsequent seasons that player had walk totals of 12, 22, 25, 15, 26, 11, 10, 14, 13, 10, and 22, until he got to his mid-thirties and lost his starting job. Only then did he start to walk at a reasonable rate; he had two seasons where he had similar walk totals (over half as many at-bats) and then he was all done.
