Yes Bannister is the guy that is really into sabrmatics. As for Melky, the reason alot of people have hope that he will one day be a very good center fielder is that he has shown over long stretches that he is capable of being very, very good in each of the three seasons he has had any significant time in the big leagues. Melky's biggest problem is consistency, he will go a couple of months where he is terrible, and does not look like he belongs on the field, and then he will go a month where he is an on base machine, and slapping doubles all over the place. If Melky can ever just be somewhat consistent he will go to all-star games. I am not saying he is a hall of fame talent, he isnt, but he has the potential to hit 300 , with 70-80 walks, and a alot of doubles, and triples. That is definatley good enough for an all-star bid. I am not saying he will definatley do that, but there is a chance, and Bannister just has no upside, and is having a very bad year as well, so what is the point.
