Well you can't argue with stats, as we all know.In fairness though, if you look at the stats, he does average 12 less than Lee and I'd say around 8 less than Shoaib. I'm not sure I'd subscribe to him being far better, but there's a case for it and he is better.
He has the marginally better record at this stage (although Lee did it for longer) I would agree, but that doesn't put him in a different stratosphere.
For me personally, Lee and Shoaib are (were) traditional fast bowlers with classical run-ups and actions.
They would always be my preference over a Bumrah type, even though I can admire his individualistic style and what he's achieved through being unorthodox.
