TC made his SUFC debut wearing 10, v Spurs at BDBL on 26/2/68, and he scored. During the rest of that season, he played in another 10 league games as a 10, plus one as a 9, and one as an 11. Also, 2 County Cup games wearing 10.
The following season (68/69), he started off as a 10, but as the season wore on, mainly as an 8. In all games: 21 as a 10, 24 as an 8, 2 as a 9, and 1 as a 12 (FA Cup 3rd round).
The next season (69/70), he again switched frequently between 10 and 8 (19 as 10 and 34 as 8).
The next 6 seasons, (after the 1970 World Cup) he always played in the 10 shirt.
I have no idea whether this was coincidence or a JH master stroke.
