To me, its Jose Reyes. He's a career .285 hitter with a .334 OBP. He's never hit more than 19 home runs and had 81 RBIs in a year. He is a huge threat to steal, but I've never understood a lot of the hype surrounding him. Great ballplayer, but in my mind, he's overrated.
My other player is Adrian Beltre, and I'm sure most of you guys know the reasons behind that.
