What he did outside Bodyline has zero validity though, because as Luffy said, outside of one series where he was genuinely ill and almost broke down and retired due to it IE the 1930 Ashes, and the bodyline series, he was an exactly conventional young pacer trying to find his way in a batting era. if those two are ignored he has the home average of 24 and 23 wickets to his name in 12 innings bowled at home and one albeit poor series in Australia with a match winning performance but faded at the end of the series after being subjugated to high workload. Regardless, it's just 12 Tests and nothing can really be extrapolated from them, especially since Barry played just 4 Tests all at home, if he was burdened with an international task as difficult as touring Australia as a pacer in the 1920s, we'd have a better idea where both stand.
Bowling on the leg is not the same as bowling Bodyline as that quote shows, Voce was bowling half pitched (short) and at the bodyline IE Torso, bowling intentionally at the body with an intent to hurt is Bodyline, hoping they'd block and give a catch to someone on the leg. Larwood was getting majority of his wickets Bowled/LBW, likely two in slips, one on deep point and one to the keeper, I've only been able to verify two wickets he got the leg trap IE Bradman and McCabe at Adeliade and even those only warrant an asterisk rather than removal. Basically, I don't really think Bodyline is some guaranteed path to success and enhanced stats than normal, wasn't true for either Voce or Allen so not sure why it would uniquely be true for Larwood.
At the end of the day, Barry played all his Test games at home where before the 1930 Ashes, the illness series, Larwood was averaging 24, even if he failed in one series overseas, it doesn't really affect Barry vs Larwood and then there's the matter of Larwood having a genuine overseas ATG series – Regardless, I think any extrapolation made on either's Test record is completely worthless given the lack of genuine sample one way or the other, remove Bodyline and I'm removing the illness-induced Ashes, we are down to 12 Tests, with Larwood having the home average of 24 (22 after the first Test of 1930) and away of 40, with Barry not having any away duties and half Larwood's home sample size.
Test comparison also just doesn't go Barry's way.
