Thanks for the help it’s something that I struggle with. It’s line the biggest question becomes what’s the more valuable position in this set up? What position to play in the flex
Assuming you have a little bit of time, some basic Excel skills, and the data, one way to approach this is to just do some basic valuations by position based on previous positional performance (I prefer at use least 3 years of data, but no more than 5, to help smooth anomalies but still highlight any recent positional trends). This particular method gives a simple valuation essentially using the worst starter method applied to a 3-5 year average of actual performance.
For this, you just need the points scored by each player for each year. Sort each year separately. Replace the names so that the top scoring QB for each year is identified as QB1, #2 QB each year is called QB2, etc. Do this for each position. Once you've done that, average the yearly scores for each "player" - ie the average for QB1, the average for QB2. As this is a 14 team league, take the score for QB14 and subtract that from the score for all QBs - do the same for TEs, K and D. RB and WR is a little trickier in this setup (in a more traditional 2 RB, 2 or 3 WR and 1 flex set up, you'd use RB28 and WR 28/42 for your baseline). Given the amount of flexibility in your lineup, I would just lump all of the RB and WR together into a combined position and use RB/WR 70 as your baseline.
This at least now gives you a way to compare values across the positions. For example, if the value of the top 2-3 QBs is roughly 60 points, but the top RB/WRs are only valued in the 30-40 range, then your idea of targeting a QB early makes more sense. But if you see that the top QB values are in the 30-40 range and the RB/WRs are up in the 60-70 range, then this shows that you clearly should focus on those RB/WR positions.
You just need to slot your player ranks into the valuations to give you a rough idea of who to target when.
If you have done projections for the season (or have access to projections you trust), you could also use those (with your scoring system applied) in lieu of the averaging method I described.
As mentioned, this is a fairly simple method to evaluate positional values. It doesn't fully take into consideration the range of decline within a position (but you can check that by looking at the values at spots when you are likely to pick to determine where drop offs may occur), but it will help you with generating a combined board that makes use of your actual system with your lineup requirements applied. I like to use it as one of my tools to have in my arsenal when prepping for a draft, especially one that is outside of the more standard setups (which your added flexibility would qualify as in my opinion)
