Single worst incident I can remember was an elbow by David Bradbury of Oldham, breaking Lee Harland's jaw. As for dirty I remember Bruce McGuire having a bit of a reputation in the mid 90's.

he left roosters for a longer contract, give over Baz

He did.

Because he couldnt quite grasp the concept that a tackle round the head was a high shot.

Too right the Chooks wouldnt offer him a long contract... he spent a large proportion of his time there suspended or injured because of his playing style.... and a player who cant play through suspension or injury is not a good player to have on your books.

So you don't rate Morley then Barry.

Nope.

Morley disciplinary record at Warrington is very good.

kurt Sorenson is possibly the biggest cowardly thug I have ever seen on a Rugby pitch. You could always count on Kurt picking on the small blokes.
Les Boyd largely mended his ways at Warrington but he hated Wigan with a passion
