In lower cap leagues, it's to your advantage to take an extreme pitchers park like AT&T, because you won't need as many IPs, which means you can allot more salary to quality over quantity. (This is the biggest flaw of the sim, using pitch count to drive fatigue). You can get by with 1250-1300 IPs in an 80M cap in a pitcher's park.
If you instead pick a park like Coors or Hilltop or Fenway or any other big offensive park, good luck with 1250 innings.
