That's just idiotic.
It's the same as normal teams with the base line talent elevated, that's it.
And not to let facts ruin a good lie, but this part is really important, they don't render secondary skills meaningless, because they all include, feature and require a batting all rounder and an elite cordon. Those remain constant. what you meant to say was that they don't feature "bowling all rounders", but they're at least 2 good reasons for that.
The disgust you write the term bowling all rounders with, it really shows how unbelievably scared you are of Imran and nowadays even Hadlee, you've been scared a long time, haven't ya?
Anyway, frankly speaking a single slip is nowhere near as impactful as bowling or lower order batting so I'm just gonna skip that. Why do we need a batting all rounder anymore than a bowling one?
The two really life best teams ever had no specialists batting all rounder nor bowling all rounders. They did have batsmen who could provide solid support with the ball to ease their bowlers, which remains a necessity.
Except they couldn't. If they had better batting all rounders they'd win more games, especially if they had a spin one. For example, QPO in 1984 in Border's game, would've comfortably won the game if they weren't forced to have Viv and Gomes bowl 52 of the 112 overs in the next innings.
And no team sees the necessity regardless of real or fantasy, to choose two specialists batting all rounders because of yes, diminishing returns. Why weaken the batting for a 6th bowling option that will hardly get the ball.
and Yeah, that's my point. Realistically if you have Sobers and Hammond you don't need a Kallis, they can share bowling duties and slip duties, sadly there's been three of them over the last hundred years born in vastly different times and vastly different corners of the world and therefore this situation doesn't actually exist for a normal team.
Therefore, of the great all rounders, none of their secondary or tertiary disciplines become irrelevant due to diminishing returns
IN THE REAL WORLD, in a fantasy world sure, but it's very much like saying if Hannibal and Napoleon were born under Phillip in Macedon they won't actually be great and just be under Alexander, sure, doesn't mean anything because their actual achievements in the real world prove their worth.
Same with the secondary discipline of all rounders.
In another thread, I've presented multiple takes, videos and articles authired by test captains, historians, statisticians, pundits and commentators alike regarding team building and all say the same thing. The priority of a bowling attack is to take twenty wickets at all costs, and that the responsibility for runs rest with the top 7 (bats and keeper all rounder).
It was also pointed out how the keeper becoming an all rounder position has pushed the selection of an attack even further away from batting consideration.
So no, it's not only because of overwhelming talent that diminishes the need for "bowling all rounders", because it happens in every day real life cricket as well.
The value isn't perceived to be there. Certainly not among a plurality far less universally.
The priorities remains, take 20 wickets, that's universal.
There's no point to taking twenty wickets if you can't outscore your opposition.
At this point you're just fundamentally ignorant to the game, teams take 20 wickets and lose literally all the time, you can't outscore your team and lose. Fundamentally, outscoring your team is important, bowling them out won't do anything if your batsmen themselves get bowled out for under 200 both digs, same way huge scoring won't mean anything if you don't take 20 wickets consistently, like this is super basic.
That's why when Imran just makes more runs, conceding a few more runs while bowling isn't going to actually do anything in comparison to a McGrath, those extra 25-30 runs and his ability to finish games, score crucial runs or fight out crucial draws is much, much more valuable than McGrath's one point superior bowling average that would amount to basically nothing.
Basically, you're saying for an all rounder, we need to ignore their actual value (contribution to both batting and bowling) and just focus on what specialist bowlers are supposed to do. Just how ignorant of Cricket are you? should we ignore Sobers's bowling too? it's not the job of a 1-7 batsman to bowl after all, it's the job of number 8-11 to bowl and dismiss people.
Like you can't be for serious, you're literally an advocate for proper keeping, have Knott in your all time XI and know that for vast majority of Cricket history keepers have been specialists, so you're conceding for vast majority of the Cricket history that bowling all rounders DID HAVE VALUE? Oh, nice.
There's actually a pretty damn clear template for greatness, it also includes a couple batsmen in the top 4, capable of going through the gears and providing impetus if not causing destruction, but that isn't convenient for your beliefs either. But continuing on that vein...
And coming back to this, do know though what secondary consideration is a constant priority regardless of overwhelming talent for an All Time team, or any of the greatest teams ever, to even an average one? The cordon. Go figure.
I don't care.
I already said I'm willing to give people credit for having higher range, and having an ability to accelerate and decelerate at will. It's you who is so ridiculously biased towards strike rate, scoring rates and all that, that you've been personally wounded by the concept of people not automatically giving people like Viv or Brook points for their scoring rate, it actually grinds my gears how ridiculous your belief is and how willing you are to be aggressive and honestly borderling unstable when people don't view the game the same incoherent way you do.
And coming back to this, do know though what secondary consideration is a constant priority regardless of overwhelming talent for an All Time team, or any of the greatest teams ever, to even an average one? The cordon. Go figure.
That's where the value is, as you have also referenced.
Want a secondary skill to focus on, focus on that one.
You know what's also valuable, lower order runs which win games all the time, varied fifth bowling which exerts pressure, gets breakthroughs and ofcourse, slip Cordon, which is a three man job tbf.
but you have decided only one matters, Sobers did bowling so a bowling secondary discipline matters to an extent, and lower order batting is done by sources of evil like Hadlee and Imran and Miller and therefore must be banished at all costs.
