Hudgell has spared nothing in his assessment of Walker’s decision to depart, and has accused the Scotland international of being an ingrate who has not fully appreciated just how much the club has helped him recently.
Walker was charged with two counts of attempting to engage in sexual activity with a child, with the charges being dismissed at Leeds Crown Court in May.
“I can’t blame any player for wanting to play in Super League,” Hudgell told the Robins’ official website.
“But in my opinion Adam is a special case and we felt he owed us a year for the support the club has given him. Instead, he was the first to head for the hills.
“It was us who sat round the table with his legal team and repeatedly defended him in the face of criticism.
“By contrast, his agent has crawled out from under his stone at the smell of cash to take his slice.
“It’s a great disappointment for the club to lose Adam but we will move on.”
