Preliminary estimate based on injuries/backups/byes as known of today is that 30% of roosters will be playing with $78+ dead money. Median is $63 (mean is $64). 10% of roosters will have $100+ dead money.
I'm currently looking at $51 dead money (McCaffrey + Waller) which puts me at the 67th percentile in terms of "least dead money this week", which seems a pretty decent place to start the week.

Updating this, I added one more category of Dead Money, which are guys who are "barely" playing... I guess technically not dead money, but mostly dead money. ("I'm not dead yet!" "Meh, you will be soon..."). These are guys who are putting up minimal points at non-K/D positions and haven't shown any signs of late that they have a chance to meaningfully contribute to a team's score in week 9.
Some of the wider-owned examples include Tank Bigsby, Van Jefferson, Juwan Johnson, Dalvin Cook, my own Isaiah Hodgins, and Elijah Mitchell. Average is $13 per team in this category.
Updated to include these guys 30% of roosters will be playing with $91+ (mostly) dead money. Median is $76 (mean is $77). 10% of roosters will have $114+ (mostly) dead money. I'm at $57, which is 74th percentile for "least dead money this week". Feeling good about that.
