You’re coming across as a bit of a glory hunter.
Teams outside the PL or top 6 are not irrelevant. Nottingham Forest have won two European Cups. Leeds are a big team. Back in the day, Wolves were the team to beat. And what about Preston? Winners of the first ever football league. League clubs have a history too you know.
You strike me as someone who has never watched the football league, if you had you’d know that there is plenty of drama in league football and it is also more competitive - a team could challenge for promotion one season, and be relegated the next. Not forgetting the fact that that is where a lot of English players ply their trade before setting the PL alight (or not, as is usually the case)
