Halligan is without question for me the worst. Can't actually speak the language, for a start. Has no insight into the game (given he was a glorified place kicker, not surprising), uses 'line speed' to explain every swing in play or momentum with one side, says 'for sure' at the end of most things, comes up with phrases as funny as a kick in the pills as an attempt at humour, overpronounces Polynesian names, stutters and mumbles...he's just crap. And has been for 10 years, yet still keeps getting a job.
Mind you, he's amongst friends in being shit in the NZ commentary team.
I can't think of a job in the world where you can be so inept for so long and continue to be employed.
