Original sentence: 審判がクズなだけ！ Google translates it as "Referee just scrap!" So if we analyze the sentence:
審判(referee) が(GA particle) クズな(???) だけ(only?)
What part of speech is クズな and what does the sentence really mean?
クズ(屑) literally means ゴミ, waste, trash, litter, garbage, rubbish... and it's often used like "crap" or "a piece of crap". I think it means something like [役立]{やくた}たず or [無能]{むのう} (worthless, good-for-nothing..?).
審判 The referee
が the case particle as a subject marker
クズ crap, rubbish
な The auxiliary verb だ
だけ！only, It's only~~
So I think it's like... "It's only he's a crap referee!" "It's only because the referee is rubbish!"

2Would you like to comment on the part of speech (品詞)? Dictionaries list it as a 名詞, and yet it is followed by な as if it were 形容動詞. – Dono Dec 22 '12 at 14:03

1Google shows lots of results for both 屑な and クズな. Is it possible that the word has only recently become popular as a な-adjective? – Billy Dec 22 '12 at 16:03

1@Dono, you must be playing the devil's advocate here, I cannot imagine that you don't know that な here is the attributive version of copula. – dainichi Dec 22 '12 at 19:32

2@Billy, yes, that might be recent usage, however, that's not relevant for the question. You can also say nounなだけ with non-な-adjectives, e.g. つまらない男なだけさ, it's just that I'm a foolish guy. – dainichi Dec 22 '12 at 19:42

1@dainichi If it were "kuzu na no da", then yes. However, try another noun: *inu na dake, which is simply ungrammatical. So, if kuzu is a noun, as dictionaries state, then that does not really explain the na here. Lets try a 形容動詞: kirei na dake -- this is grammatical. So, is kuzu also 形容動詞? If so, why do no dictionaries categorize it as such? I think there is more that needs to be said here. – Dono Dec 23 '12 at 1:35
