I don't know about there being very few to root for -- Betts, Bogaerts, Pedroia, Holt, Swihart, Rodriguez, Taz, Koji... heck, I even like rooting for Buchholz (glutton for punishment, I guess). But there are certainly an inordinate number of guys that are actively hard to root for: Panda, Nap, Porcello, Masterson, Hanley...
