Ok just to fact check. The general cricket consensus is Imran is a superior cricketer to Marshall, this is a fact.
Wisdens list at the end of the century had Imran at 10, Marshall 26.
ESPNs 2001 list had Imran at 8, Marshall at 16.
Sky Sports list had Imran at 10, Marshall at 34.
TMS list had Imran at 18, Marshall at 75.
Woodcock had Imran at 16, Marshall at 68.
Scyld Berry had Imran at 2, Marshall at 4.
Geoff Armstrong had Imran at 5, Marshall at 7.
Richie Benaud and Dickie Bird had Imran in Their XIs, not Marshall.
First off, you read to respond, not remotely to understand, and you and @themissed the entire point of the post.
Not to add, ignore the entire question.
First off there's no such consensus, and we can go through the list.
Unless you're acknowledging Imran is 16th or 18th, the least said about those two abominations, the better. Unless you belive Marshall is the 68th greatest player of all time. Let me know.
Scyld's list was i think since the '80's also has Mitchell Johnson as a top 5 fast bowler, and his all time openers if I recall correctly Graeme Smith and Viru. Think you called me insane for the Smith pick.
Geoff has a solid list... don't agree with all the picks, but we're not supposed to.
Dickie Bird has Barry which you think is disqualifying, has Pollock and Chappell over Tendulkar and the 2nd spinner is Lance Gibbs.
Benaud's exclusion of Marshall and the West Indians were questioned in real time by Nicholas. It was biased, agenda driven and racist. I make no apologies for the last one as it's backed up by more than enough evidence that's readily available on YouTube. He was the tip of the spear orchestrated by the UK establishment and press that targeted the West Indies because of their pacers.
And all that doesn't even him openly saying it wasn't the best team, but the one he wanted to represent him. Don't know how one could exclude Marshall, Knott and Murali. But if you believe, or belive that he belived that there are 6 fast bowlers better than him, again please let me know.
Would you like me to now list exponentially more credible AT XIs where Marshall was chosen and Imran wasn't? I guarantee you it's a much longer list. Don't know why you would even bring them up. Not to mention in all of those XIs there were a bunch of specialists ahead of him, Hobbs, Tendulkar, Warne, Richards. So that kinda undermines your "all rounders are always better" theory.
But back to the original question. The fact that that from the xi and lists of Gower and Crowe, two players that went against all top 5 bowlers of the era, and they both went with Marshall over Imran and Hadlee, and we would belive that they knew Imran could bat a bit, that it's possible that not everyone adds the disciplines together as you do, and glean value and importance by impact? That not everyone believes all rounders are automatically better and that it's more nuanced than that?
That Fazeer Mohammed, Christopher Martin Jenkins, David Gower, Martin Crowe, Cricinfo, Wisden, Cricketweb, E.W. Swanton and Geoffrey Boycott all have Marshall ranked higher or in their XIs over Imran, even Patrick Eager chose a bowling attack of Marshall, Lillee and Holding, that it's not quite as clear cut (or consensus) as you wish to believe?
