This post reminds me a lot of myself 4 years ago.
When I discovered OOTP 4 years ago, I had almost zero knowledge of baseball. I'm from Southeast Asia, and I grew up playing basketball. The only baseball I knew was from an old movie about Babe Ruth " The Babe."
By watching MLB games on tv, GOOGLing aspects of the game I didn't understand, reading a few books (Baseball for the Utterly Confused & Moneyball), and, of course, reading this forum my knowledge and appreciation of baseball grew by leaps and bounds.
Unfortunately, though, I still suck at playing OOTP...
