I don't know about that. there used to be no restrictions and no one bowled 3 bouncers in a row. there used to be body-line but that was a form of attack that restricted the batsman's movement or something like that. dangerous but not bouncers
the Oz and english when they had pace used to be dangerous with it. no restrictions considered or imposed on Lindwall and Miller, Statham, Tyson, Truman, Snow, Jones, Brown etc but none of them bowled bouncers all the time. some of them were very great bowlers.
the Oz were dangerous. Lillee and Thompson bowled to hurt batsmen to the chant of Oz fight songs at their grounds. Pascoe and the rest same way. yet none of them bowled bouncers 6 in a row.
Bond nor Donald did that. a bowler must take wickets to justify his place in any team. he cant take wickets with 6 bouncers in a row. that is just not possible. bouncers are a weapon of attack only if it does the job..part of a system of attack.
Griffith used to prize you up with an effective bouncer that sooprised batsmen. then had them skipping to get their toes out of the way for the yorker that spread their stumps. Ambrose too.
fast bowlers must be free to exploit the bouncer. they must learn to bowl it better. the batsmen are too coddled now, too protected. if fast bowlers were unfettered a man like Skook would never have scored all those tons. but they got him now. he is collared.
batsmanship has fallen away badly. impse batsmen now get fat on protected runs. we have no more great batsmen in the world..just like there are no real great fast men around.
the nature of the game naturally would regulate how any bowler bowls. imposed regulations stifles everybody.
only a fool would bowl 6 bouncers to Kanhai. those they did not have to fetch from the boundary Kanhai would have let pass harmlessly, unreachable to hit away for runs
I have faith in the nature of the game to regulate naturally how it is played. remove the unnecessary rules
