I just heard on ABC radio during the tea break that Benson has stated, it was a combination of the pressure the new referral system has placed on him and health issues, his reasons for leaving.
Sounds like he is a little precious by not liking having his decisions scrutinised.
I take that back if it proves to be the case that he has returned solely for health issues as mentioned in the link. But what is this game coming to if the umpires are quitting because of the pressure.
