Muralitharan didn't flex his arm more than 15 degrees. That's what matters, not the deformity.I know what a throw is. But these guys with weird amounts of flex in their arms look odd, and moreover seem to take more wickets than people with the classic ‘straight arm’ action.
Bumrah’s ‘run up’ is mostly a walk, a couple of hops, and then an awful lot of speed generated by his interesting action.
The leader of the pack in the ‘flex’ department was Murali. Apparently he had a deformity and couldn’t straighten his arm, so therefore whatever he was doing was all well and good apparently. Well that seemed to be the prevailing view, and the one the ICC went with. Another view would be that if you have a deformity and can’t get your arm to conform to the laws of cricket then that’s really unfortunate but you can’t play: the rules are the rules.
And in the case of Bumrah, well, it's quite the opposite of chucking, as his arm gets Bent while releasing the ball, instead of being bent initially and then straightened while releasing.
