Constant online anger threatens to overwhelm thrills on the pitch

Too much shouty negativity and everybody loses - hack off your audience and the road to perdition awaits.

Peter O'Mahony: Victim of a controversial clearout by Scott Barrett that wasn't reviewed in the first test in Auckland.

SPORT brings out the best and worst in us. The same occasionally applies to sportswriting. One minute it is all breathless hyperbole, florid adjectives and poetic descriptions of the best days of our lives. The next it is curtains for some ashen-faced manager and the purple prose turns to acid rain. One day you’re a rooster, as the ex-Wallaby rugby coach Alan Jones used to say, the next you’re a feather duster.

More recently social media has picked up this ancient art form and run off with it like a demented William Webb Ellis. Nick Kyrgios looks an angry man at Wimbledon but he has nothing on some of the Twitter loons howling at this week’s chosen moon. Which may explain why elite sport in general seems to be becoming more shouty by the week.
