Surely the answer is in the article then? It's talking mainly about DionKE playing:
“It just shows you how things can change really quickly,” said Robins, of the young defender who made 32 senior appearances last season.
“His performance on Monday in the Under-23s and leading up to that, and his attitude, commitment and desire are why I re-signed him in the summer and he’s showing that again now.”
He played a lot last year, became a fans favourite, signed a new contract and then we brought Grimmer in. So I can see why that might have put his nose out of joint - glad he's knuckled down and getting a chance again.
