Krob won't hurt anything by cutting his hair, I think he actually regressed since the dye job. Dude got the bat on it a few times just couldn't find the hole.

It was good to see us when a close one with these guys, they have been winning with walk offs all year.
It's not about krob. There's no krob in team. The team hasn't lost since he died his hair...ergo, he must keep the ditzy bimbo look for the sake of the team. There may be other biblical, uh, baseball scholars of the unwritten rules who disagree. They are all heretics and are going to hell.
