Agreed. but some of these soft bowlers are normal for me, and others who are able to play so many test matches are extraordinary athletes. factors like bowling action, awareness about body, stamina, strength, inner resolve come into play I think. I read that fast bowlers are advised not to bowl more than 30 over per week. just to brag about myself:), I was a fast bowler n nicknamed ‘pacer’ back in college. My problem was stamina, I could hardly bowl 4-5 overs in a day.
