Hate is a bit of a strong term, but I do have an intense dislike for certain merkins.
Past players:
Langer - partly because he was so bloody good, but mainly because he is an arrogant merkin.
Hancock - the way that he used to look like he was having an epileptic fit every time he got tackled.
Sailor - all was forgiven (though not forgotten) when he joined us though.
Gourley - only Dragons player I've ever despised. Arrogant up himself tw@t.
Lamb - self explanatory.
Brad Thorn - Aussie when it comes to league, but a Kiwi when it comes to Yawnion. Farkwit.
Matthew Ridge - THAT tackle in the 1996 GF, and a prized farkwit to boot.
Tallis - Faaark where do I start? Also self explanatory.
Meninga - "What has Rugby League ever done for me?"
The current mob:
