I'm not sure I agree with Hadlee being easily better than Imran. He was better but Imran still had phenomenal performances with the ball, the ICC all time bowling form rankings sit Imran at 3rd. I would agree that bowlers like Marshall, Lillee & Hadlee had more tools in their arsenal to adapt to conditions but from the numbers this didn't seem to matter with Imran's performances. If your Plan A is good enough do you need to change? Especially when I can take them out of the attack for someone else in an all time XI if it's not working.
I have Marshall higher than Paddles myself too but that's comparing him to the best bowler in history & Lillee is another potential AT top 5 bowler so it's not a huge issue. To put it another way if Marshall & Lillee are 10 out of 10 bowlers, Hadlee is a 9.5 & Imran is a 9.
But with batting Hadlee is a 5/10 Bat & Imran a 6/10. Marshall is a 3/10 & Lillee a 1.5/10. Is that extra 0.5 in bowling worth the trade in batting?
Most, and yes I say most, of Imran's spectacular performances with the ball, and note I didn't say all.... But most of them, and especially at home, were heavily influenced by "home advantages". You should take a look at his home and away numbers during his bowling career, namely '74 to '88, the disparity is a little shocking.
So when I say that Hadlee is easier better than Imran, yes, I don't think anyone here challenges that.
Not my rankings are different than most l, but for me it's.
Marshall | McGrath
Hadlee | Warne | Steyn | Murali | Ambrose
Imran | Donald | Lillee | Wasim |
Not that's just me, and everyone sees it differently. But even here, he's generally ranked 8th.
Regardless of how close some perceive it to be, why are you selecting the 8th best bowler of all time. If he couldn't bat, would he even be a consideration.
Oh, and if Bradman is a 10, Hobbs etc a 9, Lara, Smith etc a 8, how is Imran a 6?
He's a 4 / 10, Hadlee probably a 3, and I would also suggest you go through their collective innings, and tell me how many were actual match winning efforts.
Again, just my opinion, but if I have two bowlers alone in my top tier, or even 3 as mist have here, they are making the team.
