You could parse exactly what defines a battleground state but Nate Silver doesn't appear to agree with you

On average, Biden has lost 0.5 points in national polls since the debate, but gained 0.7 points in state polls, closing a bit of a weird state vs national poll gap we'd seen pre-debate. No signs of a tightening race overall, and Biden is probably gaining ground in the Midwest.

I'd say maybe Pennsylvania and Florida may be tightening slightly but there haven't been any high quality polls (ranked by 538) in either state since the debate until Marist showing FL +4 for Biden dropped this morning. There have also been some weird (either bad methodology or partisanish) in those 2 states since the debate.
Example 1: Susquehanna (C grade) had Trump +5 on Oct 27 while they had Biden +4 in their previous poll in late Sept. FL is close but the same firm showing a 9 point swing over the last month for Trump doesn't make me feel like they know what they are doing
Example 2: Trafalgar showing PA as even on 10/25 could be viewed as a bit sketchy as well. 538 dropped them from their rankings after they showed their work on a Michigan poll from Oct 22nd that had Trump +2. The details showed a lot of absurd things
