Always liked Sproul, sad to see him go.
Actually feel like there is still good upside in him. Obviously defensively he is inconsistent, and he makes poor decisions, but his offensive upside remains. If he ever puts it all together, which is obviously unlikely at this point, he could be a 10g, 30 point defenceman in the NHL. I remember early last season he had a couple of games where he looked really exciting.
Above all else he need a coach that believes in him and is willing to persevere through the struggles.
