Grumsh simply walked into the locker room one day, and simply stated:
"Me tha man.Me play for you. Me da big guy." Considering his size and his posture, I really had no option but to let him play. He quickly became accepted into the team, especially by the black orcs, who valued his strenght. He only has one flaw, which makes him at bit expensive to the team. That boy's appetite is one of the major expences in the team. When he isn't training, playing or sleeping, he is eating. And when he feels that he has played a good game, he has a tendency to celebrate by consuming a teammate. Apparantly this has a ambivalent effect on the team. All the orcs seem to enjoy this kind of celebration, but the Coach has a hard time getting any goblins to play for the team, which Grumsh seems to have a special taste for. Grumsh has a particular manstreak, even for a troll, which makes him use dirty tricks when things aren't going his way.
