In a recent THT Mailbag, David Gassko takes on the question of whether a move to first base by Carlos Guillen would dramatically decrease his value to the team. As a shortstop, Carlos Guillen is an elite hitter but as a first baseman, he’s probably only considered good. He concludes that while Guillen’s value to the team would go down, he’d still make a formidable and productive first baseman. He also takes into account the three year projections that are part of the Hardball Times 2007 Preseason Book. Interesting and to the point analysis here.
