Let's look at the data to see who has consistently strong/weak rosters. I've gone with five years because it covers the length of most playing contracts, plus it's about the length of time most of our football operations staff have been at the club:
| Club | Five year win rate |
|---|
| Panthers | 76% |
| Storm | 71% |
| Sharks | 59% |
| Roosters | 59% |
| Raiders | 55% |
| Broncos | 54% |
| Rabbitohs | 52% |
| Cowboys | 50% |
| Eels | 50% |
| Sea Eagles | 50% |
| Dolphins | 44% |
| Warriors | 44% |
| Knights | 41% |
| Bulldogs | 38% |
| Dragons | 37% |
| Titans | 32% |
| Tigers | 26% |
If you think wins are meaningless and only premierships matter, let's take another look at the table:
| Club | Five year premiership tally |
|---|
| Panthers | 4 |
| Broncos | 1 |
| Bulldogs | 0 |
| Cowboys | 0 |
| Dolphins (only three years of data) | 0 |
| Dragons | 0 |
| Eels | 0 |
| Knights | 0 |
| Rabbitohs | 0 |
| Raiders | 0 |
| Roosters | 0 |
| Sea Eagles | 0 |
| Sharks | 0 |
| Storm | 0 |
| Tigers | 0 |
| Titans | 0 |
| Warriors | 0 |
If you aren't satisfied with a five year data set, feel free to do the calculations again with a different number of years. You can decide for yourself whether the 52% Rabbitohs staff are doing an average or above average job, but you'll find the Eels are absolutely an average club, getting average results. Whether you think heads need to roll for this comes down to your expectations. But after having watched this club for 40 years, I'd say you need to justify why you expect anyone's replacement would do better.
