You are entitled to your opinion Sir C, however Duncan has been one of our best players all season (only behind Cowie out of the midfielders).
Yesterday he was far better than Black, who for some reason seems to get plaudits for the mediocre performances he has given in most games this season (whilst at the same time bragging to anyone who can listen that he is going to win a 'big' move to Hibs). At least Russell does not take a hissy fit every time somethings happens which he does not like. He is entitled to seek the highest wage he can (like all employees), however I agree with the club holding to its wage structure.
He does no do a glamorous taks in the holding role, and I agree that his passing could be better sometimes, however we will be the poorer for him moving on in terms of our current players and we will need to replace him with someone who can read the game (in a defensive midfield sense) as well as he can.
