'One of the worst to ever wear the shirt in any position'?
That is surely just an overstated reaction against the respect he generally receives in the light of the fact you didn't rate him. We have had some hugely toss players in the time that I have been watching City! Steve Morgan was on the pitch as one of the 'legends' the other week, for fuck's sake! Richard Shaw was a good servant to the Club. He wasn't the greatest defender we have had and definitely not one of the best all round players, but I would say he was capable of better performances than the likes of Marcus Hall. Neither are held in esteem because they are world beaters, but because they played for us for a long time.
* And, as stated above, he was a very competent man marker *
