I third the "Wow!"
I never want to celebrate anyone's firing. They hurt. OTOH, I love how ruthless this team is and how they seem to reward performance. Peters and Quinn really seem like they don't give a fig about draft position (maybe because they aren't their draftees) they have made so many statement moves. Davis' and Forbes demotions are without doubt statement moves. They had several others during the offseason as well. Previous regimes, with no coaching staffs and new front offices, felt obliged to keep these underperforming players, sometimes for years.
Davis lacked something that prevented him from turning his potential into production. I don't know if it was buy in, effort, or something else, but while it is sad for him that he lost his job, I have to imagine it is a good message to send to the team.
