Madden 21 (PS4 / XBOX One) out of the box was a bug-riddled mess, most likely due to the workplace disruption caused by coronavirus dramatically altering the experience of working at a AAA video game company.
Every patch that came out generally made Madden less of a bug-riddled mess. There were some specific pain points that unfortunately lingered for longer. The kick meter is a good specific example of things that got worse before they got better.
My biggest pain point caused by title updates was the outright removal of pattern matching for most of the year, which made playing Cover 4 defensive schemes entirely unviable. A late update finally brought pattern matching back, but that didn't happen until late in the game's life cycle.
In my opinion, the version of Madden 21 that exists now is the best version.
