I'm only suggesting the tiniest of sacrifices to the bowling to gain a huge advantage in the batting. Pollock was a bowler of the type and was a pretty magnificent one to boot. But I wouldn't pick him over McGrath because they were appreciably different in quality. There is a hair width seperating Hadlee and McGrath. I doubt McGrath would pick up more wickets than Hadlee- Hadlee managed more per match at a fractionally better strike rate in a slower era. McGrath might earn them the tiniest bit cheaper than Hadlee, but unless you think McGrath would have averaged in the teens in Hadlee's era, the extra runs Hadlee brings with the bat is going to exceed the runs McGrath saves with the ball.
That's funny because I think the opposite. You pick your best bowlers in an ATG side, having a no. 9 who can bat a bit more isn't going to help as much as having a better bowler, even if the difference is slight.
Depends on the type of game we're playing I guess. If we're fighting out close low-scoring games then a handy lower order batter can make all the difference, if you're forcing a result in handy batting conditions lower order batting can be irrelevant.
Ultimately it is an efficiency argument:
A bowler's greater benefit in bowling ability to a rival is amplified by how many balls they bowl, and typically they bowl more balls than bat. But those runs they sacrifice in batting still add up every-time they bat.
Lets say player A will bat 1.5 times per game, and averages 30 never not out - he's worth 45 with the bat per match.
Lets say he averages 25 with the ball and takes 4 wickets per match. That's 100 runs given away, 45 scored = cost of wickets for him is 55/4 is
13.75.
Lets say player B will bat the same number of times as his rival and averages 10 never not out - he's worth 15 with the bat.
Lets say he averages 20 with the ball and also takes 4 wickets per match. That's 80 runs given away, 15 scored = 65/4 is
16.25.
Player A with a 25 bowling average and 30 run batting average is giving a better balance on the runs difference per match than Player B, the difference in this case is 10 runs per wicket.
Now - if you up it to 5 wickets per match:
125-45 = 80/5 = 16 Player A
100-15 = 85/5 = 17 Player B
And at 6 wickets per game
150-45 = 105/6 = 17.5 Player A
120-15 = 105/6 = 17.5 Player B dead even.
That's dead even.
Keep increasing the wickets and player B the better bowler will start leading with better overall output, alternatively decrease the number of times they bat to also favour player B.
I like the bat deep philosophy for most fits, it is tainted as being a targeted strategy of many weaker teams (yes NZ has been one at times and I still don't want to see Tim Southee batting at 8) struggling to climb the totem pole, but SA, England and India in recent years of strength have made it more palatable to those who disliked it instinctively before in both odi and tests as being a sign of weakness. It isn't. It is strategy. Some countries seem to focus more on all rounders as against specialists, some more specialists as against all rounders.
I'm not the biggest fans of forced allrounders at 6 neither as necessarily being the best team for any one game (maybe a whole summer on road pitches to prevent injury to key bowlers where the reserves are unthinkable, but even then it needs to be thought through).
