Wash your mouth out B56 - how Harris pretty much avoided criticism is beyond me. I thought he was awful (backed up by the downward spiral his career took after leaving Utd - semi-pro being about his natural level). He was just lucky there were so many other atrocious players in the squad at the time.
As an example of his awfulness, take a look at his role in Hull's final goal at Wembley.
On the flip side, I was staggered how underrated Tom Cowan was - high quality, reliable, great personality in the squad etc.
