Recalculated: today's model on the games through each week, valued at today's point in the season. It shows what each week's games did to his value, not the values Swindlr showed at the time.
Swindlr records its published values weekly from Oct 28, 2026; they'll appear here as a record beside this chart.

His projection (9.7 a game) doesn't clear a replacement-level linebacker yet, so his value is all upside: the model's allowance for him becoming more than that, which it makes wider the further ahead it looks. It's the least certain part of any value.
