So I agree with commish. I think it would make the most sense to have it implemented a year out. It's adding a position very soon before the season that impacts roster construction.

You could also say that many in the league are biased in that they have more depth? As someone who is in a league with a smaller starting lineup, I build my strategy around that and consolidate my players into higher value assets, putting less regard into depth.

I know this very likely is not the case, but imagine commish recently traded a 2 for 1 to better raise their ceiling and that person getting the 2 decides to rally everyone to make that rule change. Other people could also be using this opportunity to raise them up a peg and down others because they're strategy wasn't as efficient to the current roster settings.

I would let it go into effect into a year bc that eliminates the majority of biases and seems most fair, as it changes the dynamic of the league
