The one thing that becomes clear when going through Marshall's record is that he probably faced the overall least quality batting lineups of any other ATG pacer. Never faced his own lineup or the stronger Aussie lineup of the late 70s/early 80s. His record against top bats like Gooch, Border and Gavaskar is pretty good though but in terms of overall lineups still this has to be factored in.
And then there is the added benefit of so much pace quality bowling support that helps his overall average and SR. So generally I see a bit of stats padding there. Yes his peak was awesome in terms of WPM but over a career that quality support probably shielded his early and late career stats somewhat as he didn't have to shoulder a huge load as a 3rd/4th seamer.
Marshall is still no.1 in my book but he is not as far ahead of the others as his raw stats make out.
Ahhhhh.
For the record I rate Sobers the 3rd best batsman ever, the most versatile bowler of all time and one of the top 5/ 8 or so slip fielders / catchers to have played the game.
I believe there been 4 great phenomenons to have graced this game.
Sir Donald Bradman
Sir Garfield Sobers

He sits among the two man pantheon of our sport.
I personally, genuinely, "unpopularly" and unapologetically believe Marshall belongs in that conversation. The best batsman, bowler and all rounder.
Of all players in the modern game (with multiple credible opponents) he along with Tendulkar has the most well rounded records, home and away (yes all the top tier guys are close), with success against everyone and in all conditions.
Marshall faced off against, Gavaskar, Gooch, Miandad, Waugh Sr and Border. Plus guys who in other eras would have had much more enterprising averages like Gower, Smith, Crowe, Taylor, Boon, Jones etc.. of note though, and unlike the other bowlers of his era, he never faced any minnows to lower his numbers. To those who counter that he never faced his own team, and as with the Aussie batting line up vs Warne, who do we really think benefitted from that missed opportunity the most?
Between his skill set, conditions tested in and record, he is unmatched. He conquered on pitches meant to neutralize him and for those who believe he was protected by the other bowlers, look at his wpm at his peak, Garner's performance before and after Marshall came along and the amount of games missed by Garner and primarily Holding during his career. Walsh wasn't nearly the bowler he would become and Ambrose only ascended as Marshall declined. He protected them.
Marshall lost 4 matches in his career as an opening bowler... The Bob Holland match at Sydney (which inspired him to learn the cutter from Lillee), vs Pak in '86 where we got lbw'd, sorry bowled (I'm kidding) out for 53 on the last day, '87 in NZ where he was hobbled for the series (and didn't even bowl in the final innings) and the Border match in '89 where he still managed 5/29 and 1/17 in the flattest of conditions, vs a strong batting lineup while the others just didn't show up.
But when he didn't play, we lost.
He adapted as his career progresses, he started with the out-swinger and quickly noted that success in most conditions would require both, so he learned and mastered the in-swinger as well. He leaned the cutter from Lillee to better counter spinning or slow conditions and to even perform better later in innings. He learned everything he could, then subsequently passed it down to everyone he could.
He was brutal and unyielding, but also among the most cerebral, he worked out batsmen weaknesses quicker than most and exploited them mercilessly, not to mention, like Warne he often set his own fields.
Statistically, anecdotally and by peer rating (along with Wasim and Warne making both the Cricinfo and Wisden all time teams) he was the best. For our top 100 rankings as I was being skewered for having the audacity to place Sobers first, I also said that I have a top 3, and quite frankly the order isn't set in stone.
In a sport where there's arguments that bowlers have a slightly greater value and importance than batsmen, and for the man who for me is the greatest and best bowler of all time and, (along with Richards) propelled his team to, at the time, the greatest team ever (and even now a top 2 team), he doesn't deserve at least an argument for a seat at the table?
He knocked the bat from Sunny's hand, broke Gatting's nose and sadly ended a career, yet he mesmerized with swing and seam on the slowest of pitches. He possessed ferocious pace, banana swing and an excellent cricketing brain. He tested your technique, your will and your courage in ways probably only Lillee and Lindwall ever has, but for longer and better. To quote, he had all the toys and knows how and when to use them.
