You have the basics correct. A bunch of LHP's and LHH's in a lefty HR park. Your 4th and 5th SP's will get shelled, of course. Especially since everyone else in your Division is in a hitters park. You need to hope that your offense can overcome those days. I doubt they will given your weak pen. R1's only. They will tire quickly.
I would take (at least) $6M from your offense and get some better pitching. Make it more in line with a
Secret Formula team.
