I think in reality he has already lost the team today. .They may try to hold together another game. They are not running the game that the players built their hope and confidence around,- the approach coaches hyped all year and that the players bought into. It seems to me, each game has gotten farther away from that model. I know muschamp's patter has. On top of that, some of these guys will have had varying degrees of being let down by adults, authority figures saying one thing and not following through.
Also read that Muschamp said something , maybe today on TV (?) similar to What we need to do now is stay the course
. No mention of QB change ( no sruprise there) and said they would be teaching tackling this week.
As an edit, I want to add, I think the team will try to hold together, but I think he has about sucked the heart out of them.
