At 140M, your pitchers are going to do worse across the board. 140M is more than double the salary of the average real life team (go ahead and load up some 2013 teams in your draft center to get a feel for what a real team is worth).
If you look at your pitchers' performance histories in OL's, the walks are pretty reasonable. Still higher than real life #'s, but of course OL teams are also quite a bit better than the average real life team (80M plus AAA, so we're probably talking around 90M in salary for most OL teams).
Seriously, if what you're after is sim stats that resemble real life stats, join a single season prog, or a theme league with a 60-80 (no AAA) salary cap.
