I don't really play in extreme parks but I build the best team possible with my front 20-22. The last 3-5 spots may be determined with the ballpark factor as a tie-breaker. If I was in an extreme hitter's park, I'd certainly put a lot of weight into GB for pitchers. In an extreme pitcher's park, I'd want speed on the basepaths and a catcher with a good arm.
I assume one can claim whatever heritage they want to claim. Our Prez is considered black although I think I'm blacker than him. I don't follow hookey, eh but I imagine that position plays a role just like in every other sport. Teams want to put ***** in seats so scoring/fighting seem to be good draws.
