I checked West indies bowling. It isnt as bad as people are making it out to be. They have 2 150KPH bowlers and babar has struggled against express pace in recent times.
Rizwan hasn't struggled in test and odi and to his credit he has proven me wrong over the years countless times since he is a terrific test batter and an okay odi bat.
But he isn't a conversion freak. 50-70 is his max limit. The 100's he scored were all against extremely crap bowling on extremely easy pitches of which Abdullah and Agha also scored centuries. Agha is a good player but Abdullah isnt for obvious reasons.
