Haener starts vs Commanders: 1 INT, 5 punts ; Rattler replaced Haener in 2H: led to 19 points

I’m trying to interpret this post. Specifically the ‘then’ Broncos, Chargers, and Bucs.

It’s mid-December and those are 3 playoff teams if the dance started today. Were they not playoff worthy teams when we faced them?
What I'm saying is that Wash is a better team now than any of those teams were when we played them with SR @ QB so Haener's test will be harder than SR's was when he started
