Why does it necessarily say anything about the culture? Have we heard any player bitching about the coaches, trainers, locker room or anything else?
I think there are valid reasons that have little to do with the team itself for players not to want to stay in DC. Money can always be a big factor. The location may be a big factor - let’s be honest, there are a ton of great landing spots in the NFL that in terms of weather, recreation, cost of living, tax codes, etc… Washington simply isn’t an attractive alternative to.
There seems to be a lot of drama around this team (maybe that’s changing, remains to be seen), the media is downright hostile, and at least up to now, we aren’t a perennial playoff team. That’s probably the only thing that’s theoretically within the teams control.
I think Scherff decided a while back he was going to maximize earning during his career and that’s what we’ve seen.
