For arguments sake Jimmy Rollins is a career .332 OBP. So it goes to show that you can obp less than .350 and still win an MVP.
For the most part I have been impressed with Taveras overall game this season. When he has gotten on base he is dangerous. He knows how to run the bases and creates havoc. Just watching yesterdays game I was impressed how he went from first to third on a bad pick off throw and you could see him rounding second base and catching the 3rd base coach to determine whether to stop or not.
