I agree, MikeT, and I think the OP was valid and likely helpful for new owners.
To add to that original intent:
I came into my first HBD season with nothing but several Sim League Baseball spring training seasons under my belt. One thing I had observed there is that lower scores contribute more to expected winning% than higher scores at the same run ratio (i.e., 4 runs for, 2 runs against had a higher expected winning% than 8 runs 4, 4 runs against - even though each case had the same ratio of runs scored to runs against). I had played around with several roster types in SLB. (only in the free Spring Training leagues, so there was always SSS bias, but...) I had the most success in pitcher's parks with good pitching & defense. That, along with the expected winning% thing I mentioned before led me to pick an extreme pitcher's park (San Jose) and build for pitching & defense when I started 15 seasons ago in World Bench.
Then, I read in the guides and forums about the impact pitch calling has on OAV/ERA/overall run prevention, and noticed that high PC catchers were pretty undervalued.
Before my first season started, a veteran owner posted that a SP "needed a change of scenery." His ratings looked pretty good (based on very little experience, I thought he'd likely be my 2nd best SP), but he had just lost 20 games the previous season with pretty horrible ERA and WHIP. So I traded for the SP, giving up only a prospect I liked at the time (but after several season I realized he wasn't as good as I thought at the time).
I assumed (and I think I checked to confirm before the trade) that ballpark, defense, and catcher's PC had all more or less contributed to a decent/good pitcher having horrible stats, and wanted to use him as an experiment for my pitcher's park, good D, and high PC plan.
These were his numbers the season before: 3W-20L, 6.50 ERA, 1.71 WHIP, .304/.375/.498 avg/obp/slg against
First (and only) season for the San Jose Aces: 13W-11L, 3.42 ERA, 1.33 WHIP, .239/.317/.402 avg/obp/slg against
Another benefit in trading for him (even though I didn't understand how it worked in HBD at the time) was I thought he would either be a deadline trade chip or a type A/B FA, since he only had 1 year left on his contract. He ended up being a type B, and somebody excitedly signed for him (which probably wouldn't have happened if he had another 20 loss, 6+ ERA season... but then, without my park, defense, and C his numbers regressed to low 4's ERAs and decent-to-bad results for the rest of his career.
He was a big reason why I stuck with my plan. As MikeT mentioned, this is one of many paths to success (and it took me to back-to-back WS rings).
Now I'm trying the other extreme with a team in Colorado... we'll see if I can match the success with a very different approach!
