It sounds like I'm biased, but Joe was the best timer of a tackle I have ever seen - his record of no bookings for about 15 consecutive seasons (or whatever it was) backs that up.
Plus, he had all the attributes of today's modern, attacking full backs with his runs up the wing and great passing.
As an added bonus, his ball juggling was first rate too - keeping us entertained when there was a stoppage on the pitch.
