I'm all for more OBP -- don't get me wrong -- but Greene is a marked upgrade over Theriot, and that's really the point -- find upgrades for the weak positions, SS, C, CF, and RF. Given that RF was the best of the bad bunch, and C is covered by Soto, SS and CF are the best places to upgrade the team. MLV indicates that Greene is a 17.8 run upgrade over Theriot, that's a nice upgrade. So where's the problem? I'm pro-Green. He's got flaws, but he could be such an enormous improvement over what the Cubs have at SS, that it could be a bigger upgrade than just about anything else they do this year.
