I really feel that he scored an additional 10 runs each inning through sheer running between the wicket skills. He was a machine between the wickets. He would also score lots of help yourself runs by running the ball down to a vacant third man area for 2 or 3 and sometimes 4.
Peter Taylor was a better spinner than him and should have had his spot in the test team. Mathews did not bowl darts as he tried to flight it - but he had no loop, he did get drift but not a great deal of spin and he had no guile or cunning. He was a poor bowler and was kept in the team because of his batting.
I am judging him on his primary function which was to be a spin bowler.
