This isn't going to be a popular answer, but yeah.
Top 10 definitely, and this isn't my opinion, but no one ranked him when he played or even well after his retirement as highly as he's rated here, where he's generally around 3rd.
The first tip off is that he literally never makes any all time teams. Even from layers of his era, he's always missing. And it seems he was rated more highly as an all rounder than as a bowler, and even then behind Imran and Botham.
I've gone though a ton of lists, articles, interviews, a lot of reading, asked former players. From his era alone he's behind Marshall and Lillee, even from the subsequent era his trails behind Ambrose, McGrath and Wasim.
I can say for sure, but it could be a little like Sunny where he's seen as a "fair weather" operator, and that's reflected a little in the comments for this article.
A few other reasons have popped up, but not from enough sources to definitively make any assumptions.
Again for me he's still 3rd, but definely not in the same tier as the top 2 and not in the GOAT debate, that for me is between the aforementioned two, if you want to include Barnes and possibly for some, the two spinners.
