Nah, some of his best knocks were against quality bowlers. Was a nightmare for Vettori, Muralitharan, Steyn, etc. (he just hit Muralitharan for a 4 and a 6 in the legends league game while I am typing this
).
Still can't forget that 105 off 70 odd balls against SA in SA. The pitches in that series were difficult and all our batters performed very poorly in the 5-match series except Yusuf. Also scored a match-winning 50 in that series(played only 3 out of 5 games).
The issue with Yusuf was that he was never a number 7 batter in ODIs. His best knocks came when he was sent in early or had to come early due to top order collapses. Even in the IPL, he only did well when he had enough time to settle in.
