Colby 2012 awful and Colby 2013 one of top 3 CF in AL IMO ending with .840 OPS, relatively cheap compared to guys like Jones/Upton and solid BAPIP numbers. Steady D. Colby 2014 who knows? He has 9 dingers and an ever alarming K rate and hurt.
A great 3rd basemen is all about reaction time - arm and quickness. 2 requires more lateral movement. Lawrie could be great at 3rd and + at 2nd in my opinion over time.
