Re: Juan Francisco
I see Fransisco and just think "LH Marcus Thames". They're even built the same way. I think Fransisco will have a decent major league career, in that he'll be in the league for a while, but his best case scenario is Ruben Sierra.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
