Players understand they'ill get pelters if they're underperforming. They should avoid social media if they don't want to see it. The fans are entitled to say what they want within the realm of free speech.
My advice to KC is to remind yourself that every player gets stick. I see even last season's and this season's top scorer is coming in for some harsh criticism. The last thing you want is a family member getting on social media and slagging off your critics among the club's fanbase.
I happen to think that the criticism of KC is overdone. Yes, he drops a few ricks now and then, but who doesn't? He's become the whipping boy and scapegoat and it's unjustified.
No expert me but he was square on for Salford's first goal. Body shape all wrong. For Salford's second, it seems Robertson failed to track his runner, Warner failed to read the danger and cover, and Slocombe failed to palm away.
