18 matches isn't a huge sample size. The majority of them were played after his golden period in ODIs (pre 1998).That doesn't explain the flogging he received in ODIs from Indians.
In fact, Warne's ODI career can be divided along very similar lines as his test career, with the exception that he didn't play as long. Pre-1998 he averaged 22, taking 130 wickets in 80 matches (1.6 wpm). Post-1998 he took 160 wickets at an average of 28 in 114 matches (1.4 wpm).
But comparing ODIs to tests is like apples to oranges. It also doesn't help your bloke's case either, given the way he was belted by Australians, particularly in important matches.
