I have been working through some things and gave a few thoughts
The 5 mid season byes might be fielding no rookies if you structure right. If I am right in this thinking, it might pay to be more mindful of teams having the bye versus players themselves.
How I got to this conclusion was:
I think many teams will have 8 starting proper premiums. Then we have the big 5 mid pricers that we are all banking on to be keepers. I am also starting 3 other mid pricers - Short, Peatling and Parker plus 7 onfield rookies.
Let’s assume that of those 8 MP’s, 5 become keepers. therefore starting with 13 premos +3 MP’s plus 7 rookies. between rounds 5-11, assume we can create 6 premos. I am assuming 5 will come from rookies (15 starting rookies, 3 per premo) and one will be converting a MP. Therefore going into R12, we can have 19 pros + 2 MP’s. In a best 18, therefore if we have only 3 players with a R12 bye, then we would have no rookies on field.
If we can add 1 more premo in R13, then we can have 4 players from those teams and have no rookies on field. 20 premos plus 2 MP
Across R14-16, we should complete our sides with 22 or 23 premos. (I question whether F6 will ever be actually a premo! ). We could then have 5 players from those sides and field premo only.
Teams completed quicker than this last year. If you can complete quicker, clearly you get one more R12 and one more R13 premo and still achieve a rookie free line up.
Looking at this, R16 had only B Smith from starting lineup. So I suspect that we could end up in a situation if we have too many R12 premos, then we might find ourselves needing a rookie score or two in R12, but benching a premo in R16.
(The other interesting part for me was by starting Bont, Brayshaw and Dawson if I needed another starting premium in the midfield, they all had a bye in R2-4. Very limited choices)
Anyway, that’s my thinking. I have managed to structure accordingly. It is not as good looking as some sides on paper, but if it can hold its own, then I might have an advantage in the mid season byes.
