McGrath also had a great peak.Hadlee during his peak in the mid-80s would also be ahead of McGrath. If he take peaks, this isn't close.
5 year peaks
Hadlee (83-88) 33 matches 193 @ 18.39 19 5’fers
McGrath (99-05) 55 matches 257 wickets @ 18.78 12 5’fers
Hadlee’s peak is better but “this isn’t close” is stretching it.
(note: Hadlee’s numbers go to 192 @ 17.98 if you exclude his first innings 1/98 vs England in the first match of this stretch - however I don’t like splitting up matches in terms of peak stats tbh)
