It's not that unfair actually. On first glance, stats would make it seem like they're both roughly equal.
Averages
Younis: 52.4
Dravid: 52.3
Younis Khan has 20 100s in 76 matches, which rougly equates to a
century in every 3.8 matches.
Dravid has 36 centuries in 164 matches which is a
century in every 4.5 matches.
vs England
YK: 43
Dravid: 41
Equal for sake of discussion
vs Australia
YK: 31
Dravid: 38
Winner: Dravid
vs Saffers
YK: 47
Dravid: 35
Winner: YK
vs Sri Lanka
YK: 52
Dravid: 48
Winner: YK slightly
vs New Zealand
YK: 60
Dravid: 45
Using these stats, one would think Younis Khan is statistically superior to Dravid, except against Australia where Dravid has pulled his weight; whereas YK takes the cake in Africa, SL and New Zealand
Having said that, Dravid has played twice the number of matches that YK has, so obviously stats would not tell the whole story, but looking at whatever numbers we have, we have to accept that YK wins this one, or if going for the benefit of doubt, we can change the verdict to:
Verdict: Younis Khan is statistically equal to, or marginally superior to Rahul Dravid
And to be honest, I wasnt expecting this; I was expecting Dravid to win this one by a landslide when I started stat-hunting. Stats are a funny thing
