To clarify bro, I never said no.8 is a designated AR spot for normal teams, but no.8 is expected to have batting ability at least to the level of useful tailender. So Warne or Marshall is good enough at no.8 for normal teams.
In an ATG team context, that batting ability will be near or at AR level rather than useful tailender.
I think you would agree rather than having a tail of bunnies.
That's your call. Logically though they should be of different values.
In the real world I have seen far more harm to having a bunny tail than a less competent 5th bowler. Virtually every team has a no.8 who at least is a useful tailender.
Let's not debate slips now.
Want to address every point.
For most of history, I don't believe most teams picked their attacks taking batting into consideration. You just align them in the order of their ability.
Again, there's a split even here on whether or not batting even factors into AT bowling selections, the last time we did a vote, Hadlee and McGrath tied for 2nd, Imran and Wasim was a fair bit behind tied for 4th.
True no one wants a tail of bunnies, no one wants a 5th bowler that relives pressure and gets taken apart or a slip cordon that drops everything either.
Umm, that's interesting. If your team is harmed and actively negatively impacted by your tail, I would suggest that you have bigger middle order issues, but yeah. There's no doubt that the tail can from time to time provide some useful runs and save a match, but it's not something that's they're consistently relied upon for.
A poor fifth bowler on the other hand can derail an entire attack. If they come on and gets taken apart, it relieves pressure, gets the batsmen into a rhythm and if they have to be taken off, totally wrecks the rotation and forces either a worse bowler into action, or one of your primary guys back sooner than you would like. And yes, every attack needs at least 5 useable options.
It's weirdly coincident that as I'm writing this and rewatching the play from last night that it was mentioned that Australia dropped 74% of chances in the last series which was the highest percentage since 2008, and they lost the series. I find it hard to believe, that anything of these 3 disciplines causes more real world harm, that having a cordon that drops everything, or even half of everything.
So yeah, in terms of causing real world harm, think having a competent no. 8 may actually be last.
In terms of having real world positive impact they may all be equal.
Yes, virtually every team has a useful tailender, most also have a decent 5th and cordon etc. though I would prefer the cordon to be considerably better than decent.
Just because the masses repeats something, doesn't make it true. Guys like Hammond and Kallis who contributed to two of those fields are are just as useful if not more so than those no. 8 guys that are so revered here.
