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 (6.3 a game) doesn't clear a replacement-level defensive back yet, so his value is all upside: the model's allowance for him becoming more than that, which it makes wider in a player's first three seasons. It's the least certain part of any value.

What managers actually gave for Jason in completed trades in public Sleeper leagues, leagues like Dynasty IDP first. Each shows the date and the league's settings; the price is what was agreed then, and the line under it is today's value, a different thing. Two-team trades of up to four pieces a side; none is left out for disagreeing with Swindlr. No league or manager names.
