I'm sure you meant The better IF lol. But anyway...I'm sure everyone is going to say Team A, but let's take a closer look.
Team B obviously has the better catcher. I would say 1B is pretty much a wash, but I think Berkman has the potential to out perform Teixera. 2nd base is interesting...it could go either way, I think Upton has more potential though. 3B goes to Team A, but Aramis isn't too bad of a consolation prize. SS is the only area where I would say Team A dominates Team B.
So if you really break it down, you'll see both teams are pretty close.
