Any pics? My first suggestion would be to get a ProPlugger and use it to transfer plugs from your denser areas into the large bare spots. For any small bare spots, let them fill in by themselves in the spring with some help from nitrogen. Seeding in the spring should be a last resort, in my opinion, unless it's really bad. You won't want to skip that spring pre-m.

I have a lot of poa a in my reno. Tried hand pulling but there is just too much. I'm doing a round of frequent tenacity apps at a low rate to smoke as much poa as possible before winter. It's much easier to kill while it is young and pre-wintered. Depending on how bad it is in the spring, I might continue tenacity or go with my backup plan, ethofumesate. The summer heat should kill a good bit of it and solid pre-m barrier will prevent all the seeds from germinating again in the fall. My steps are documented in my journal.

 

If you want to do spring seeding in particular sections use tenacity as temporary pre-em in those areas, spray the rest with prodiamine. Do follow-up apps of tenacity 1 month down and at 60d put down prodiamine.
