I'm admittedly not a good sports bettor (I do love to gamble, for sure) but I've noticed just how good Vegas is at setting the lines for games. The pros can sniff out a bad line enough to shift it by the time that you, the amateur, get to bet on it - so it's almost just not even worth it to me. I have a lot more fun with the fantasy stuff, or even dumb prop bets just for fun.
