Hogg said Bradman wouldn't have averaged his famous 99.94 if he was playing today.
"It's disrespectful. I know to say that, but those stats jumped at me that it was easier to bat between 1920 and 1950, than what it is now," Hogg told 'SEN Radio'.
"Sir Donald Bradman was a freak, but I don't think he would have averaged 99 now."
"(It's) just very interesting the batting averages England have had in current times, Graham Gooch has got 42, (David) Gower has got about 43, (Allan) Lamb is mid to low 40s, Geoffrey Boycott's 47, (Kevin) Pietersen 47," Hogg said.

"I'll go back between 1920 and 1950, (Walter) Hammond averaged 58, (Herbert) Sutcliffe 60, (Len) Hutton 56 and (Jack) Hobbs 56, so there's four names I've just come up with, who've all got averages 10 above all the current-time players.
Hogg's comments caused a stir on Twitter as fans expressed their opinions.
Widely regarded as the best cricketer ever, and Australia's best-ever sportsman, Bradman holds a special place in the hearts of all Australian sports fans.
