Good, I have seen a direct correlation with guys concentrating more about hair styles and hair maintenance etc and deterioration in play.
Josh Donaldson short hair, good, long scraggly hair, bad..
Marcus Stroman, regular cut without dye job good, with died trendy style bad.
Russell Martin, normal hair, good. man bun and fro, bad!
Jose Reyes, normal hair good, Rap video and trendy cut... Bad.
LG jr... Good offensively, bad on D with the long hair, probably getting in his eyes -.. Guaranteed too see all around improvement after hair cut..
Travis- Normal hair , good, goes to Marcus Stroman's stylist and dyes it.. Bad!
