Well that's the point though. If Smith was significantly worse than Sehwag against the best bowlers of their era, how is he meant to be a better option when playing against Lillee/Marshall/Hadlee etc. At least with Sehwag there are a bunch of standout performances like his 150 odd vs McGrath/Warne/Gillespie, 3 100s including a triple against Steyn, a couple of massive double 100s vs Murali, 2 hundreds vs Pollock, a match-winning triple against Akhtar along with a stellar overall record. Smith averages in the low 30s with just 2 hundreds in 38 innings with one of them being against a post 90s Waqar. Except for Asif, he fared far worse than Sehwag against almost all of these bowlers. The stats are filtered from 2002-07 for Smith because all the Tests that he played involving these bowlers were within this range.
When did I say that? May be I am getting something wrong here...
Anyway, coming to the argument, you have mentioned great knocks of Sehwag...let's dig them up a little bit, there are 9 knocks mentioned in there (correct me if I am wrong).
155 in Chennai, India vs Australia
319 in Chennai, India vs S.A
293 in Mumbai, India vs S.L
164 in Kanpur, India vs S.A
109 in Nagpur, India vs S.A
165 in Kolkata, India vs S.A
201 in Galle, S.L vs S.L
319 in Multan, Pakistan vs Pakistan
and
105 in Bloemfontein, S.A vs S.A
Now I believe in my post I had clearly stated that In the Indian sub continent and in Australia this Hayden-Sehwag combo is fine, elsewhere Smith has to get a look in...you are only making my point stronger with so many centuries
by the way, the only century that you mentioned outside sub-continent was that 105 in Bloemfontein, that came when Sehwag was batting at 6...
