This opens a can of worms around the question whether the likes of Hadlee or Murali's average would have been better, around the same or worse had they had better bowlers at the other end. Obviously it would have impacted their very high wickets/per match numbers, but what about their average? One could argue either way on that.
I would like to have a go at answering this question once and for all. I kid about the once and for all as I am just one analyst on the site, however I have a hypothesis anyway about this issue that although it needs a bit more testing I believe it to be correct.
Essentially the lone wolf bowler has a higher wickets per match. But also has a higher average and SR than a bowler that gets to hunt in a pack.
Here is the analysis which I have cut and pasted from a stats mad thread we had on this topic 3 years ago. It was me and Migara vs Ikki iirc.
Hadlee
% of innings SR Wickets Wickets per inning
<100 balls 23% 38 58 2.64
100-150 balls 27% 41 124 3.0
150-200 balls 29% 55 137 3.1
200-250 balls 15% 64 75 3.4
250+ 5% 60 37 4.6
Overall SR = 50.8
Marshall
% of innings SR Wickets Wickets/inning
<100 balls 35% 34 114 2.1
100-150 balls 41% 51 150 2.4
150-200 balls 20% 52 98 3.3
200-250 balls 3% 76 14 2.8
Overall SR = 46.7
No two bowlers have equal abilities. Most believe Marshall to be better than Hadlee, for the purposes of this analysis I have labelled them as bowlers of
similar ability.
The less deliveries either bowler bowled in an inning the better his SR (and average) was.
76% of Marshall's innings were ones where he bowled less than 150 deliveries. The average SR for innings less than 150 deliveries was 43.
Only 50% of Hadlee's innings saw him bowl less than 150 deliveries. Hadlee's average SR was 40.
Hadlee had the better SR in large part because he took more wickets on these occassions based on not having to share with anyone else.
This on the face of it would suggest that Paddles' SR benefited by being a lone wolf but wait I am not finished yet:
24% of Marshall's innings were greater than 150 balls. His average SR in these instances was 55
50% of Hadlee's innings were greater than 150 balls. His average SR in these instances was 57.1
Because a higher percentage of Hadlee's innings (50%vs24%) were greater than 150 balls his overall SR gets dragged and this "dragging up" is more powerful than the SR benefits he gains for innings less than 150 balls.
A couple of small comments.
1) Why did Hadlee have more innings with greater than 150 balls. Because he had no one to pick up the slack on days when he didn't perform. He was a lone wolf. While the Windies always skittled people because if it wasn't Marshall it was Garner etc.
2) Why are SRs higher when you bowl more deliveries. Shouldn't your SR remain constant. No. When you are involved in an inning where you have bowled a lot it means that the opposition may have scored 450 for 5 declared and simply not have gotten out as much. Either way in those innings the batsmen lasted longer and sold their wickets more dearly. This point may be obvious so apologies if sucking eggs territory.
Conclusion Hadlee would have had a lower average and SR but less career wickets had he had more support in the bowling.
Note I have linked SR and average in this analysis as they both have the same dynamics.
