I noticed that about quite a few sports... there's a kind of permissiveness about players acting up because it's understandable to get emotional when you're pumped full of adrenalin (even the fans get out of hand, yelling at the ref and stuff). At the same time that's precisely the reason it's drilled into players that they have to abide by a higher standard of conduct so as not to compromise the institution of the game... so yes, it's human to act that way but it's not "ok" from a professional standpoint.
PS. If you can, try your hand at giving some of the others a bit of feedback. If you already have, thanks, can you do some more?
