Our player of the season just gone by a stretch (not meaning to damn him with faint praise, since we were largely toss and went down). Played all season at centre back, but can do just about as much of a job as right back. Will run all game, can go past players with a change of pace and think about bringing it out of defence, not flash but doesn't waste a lot of possession, gets some crucial blocks and tackles in. He is not invincible and has made mistakes, but our season has been riddled with them all over the park. If he continues in the same vein of form with a better team around him (let's be honest, for all the shouts of 'anyone can beat anyone in the Championship', the table doesn't lie), he would be a good acquisition at something like the price you quoted. Word to the wise, offer half that and our board would probably accept.
