Pull ratings.   Change them.  You'll notice a change in stats.   Of course, you won't keep your best pitcher in the game as long on occassion but that's how otherwise successful RP end up with "bad" stats.    And, of course, everyone wants their best pitcher in the game until he hits his PC(which is probably too high).

A good relief pitcher is the easiest thing in this game to get, mainly because everyone under 20 stam is basically ignored, and you can draft future closers in the late first round/early 2nd rd while everyone shoots for the good or even mediocre SP or position player.

On my Wichita team, I've got the league leading ERA in ML and AAA, a lot thanks to the bullpens.

Over the two teams which have 7 ML quality relievers (now or future);

1 drafted 11th
1 drafted 12th
1 drafted 16th
1 drafted 32nd
2 drafted 36th

One an international that went for 8.6M (which is a little excessive, however...)
They are out there if you really want them.

Further, I'm seeing a few people that should know better not planning for their park.

Like, say, having 11 pitchers in a park that gives up more than the avg share of non-home run hits, thus the pitchers see more batters. Just saying.
