Boras bank account is sure going to grow this off season with Beltran and Beltre getting huge contracts. You can defiantly make a case for Beltre to get some NL MVP love. When it's all said in done I think Rolen will get the nod. Great offense numbers and night after night outstanding defense plays.
The only problem with Rolen is if you take him out of that line up the Cardinals still would have a solid team. If you want to use the "Look at the talent" argument with Beltre then you have to use the same one for Bonds. As he has even less. Not to mention he never gets a pitch to swing at.
