This is the crux of our disagreement. I have just seen teams more negatively impacted by a bad tail and have more upside from their extra runs.
The 5th bowler isn't going to save an attack if the first four bowlers failed. He just needs to be good enough for rest overs and frankly most teams can have one or two bowlers capable of doing that.
Stop mentioning slips please.
So, genuine question. What do you consider being negatively impacted. The lower order not scoring as high as the top order? Because that's not a thing.
The team failing to get competitive scores? Because against that's the purview of the top order.
Even the examples you gave about the 5th bowler saving the team, that not the primary, nor regular responsibility of either.
Now if you're talking about having a bunny tail and getting near to no contribution from them,
1. I assume you're getting bowling contributions from them to make up for the short fall, and
2. Not sure how much that's happened in any event.
I asked someone earlier if they would take Kapil over Jasprit if they could only have one, don't think anyone's going for the batting in that scenario.
With regards to the slips, no.
Last night ee literally just saw India's innings where every wicket but the 10th, fell to catches behind the wicket, where btw Australia was perfect.
To ignore or discard it not only ignores an important aspect of the game, but it denigrates the practitioners of it.
It also makes away one of Kallis's skills in any comparison.
So for a country like Australia, England, New Zealand or SA where most of the dismissals are taken behind the wicket, it's just as important as any other secondary skill of not more so.
The great WI, Australia or SA teams relied more on their slip cordons that their lower order for victories.
So no, I'll not stop talking about it.
