Here is some data from 2017 and prior for a couple of years...

I did a much more simple thing a few years back, without the captain scoring analysis, simply looking at top 6/8/2/6 in their position and found a reasonable turnover as well. The thing that I think this analysis needs is an adjustment for age. Because you would expect that variability to occur, because its well understood the scoring profile drops off pretty smartly after 30 for most but the blessed. I would be super interested if this could be accounted for. So if you could do some regression to predict for age score movements ex ante it would be sweet!
Intrinsitcally I think its well understood, especially in the forwards and defensive lines. People aren't just running to slam Sidey/Hawkins in this year. We know there will be change.
The other thing that was super noticeable was that positional changes from Fwd>Mid and Def>Mid explained a lot of movement in the following years top 6. But even accounting for that movement there was still significant turnover.
Cheers
PS: looks at team (which has transitioned from a MPM rabble back to GnR, spies 4/5 top priced mids. Sighs. Newton's cradle anyone?
