Also, scouts have hilarious stories about players. I remember a guy telling me a couple years ago that he'd been friends with Bartolo Colon since before he got signed. He told me Bartolo would sometimes call home and tell his wife to have his workers roast two pigs because he had some "visitors coming", but he just wanted to eat the pigs himself. Obvious hyperbole, but considering some of Colon's eating exploits, having them roast one is not something I'd put past him.
Adrian Beltre is another one I've heard a lot of stories about binge drinking in his younger days. But the funniest stuff is about Nate Mclouth (Remember him?) for when he came to play in the DWL.
