you gotta make good picks to win, it doesn't matter if they're favorites or not
I have no problem taking a - 200 favorite when it's a scorching hot team playing against a really bad team on a terrible losing streak
I want nothing to do with a - 200 favorite if it's lincecum pitching with that godawful giants offense
You gotta play the right favorites, just like you gotta play the right underdogs. Neither style of betting is better, it's all about what you're comfortable with
