Frost is a Madden player type coach.
His M.O. is flash, hype, focused on excitement and hype and splashes while ignoring the details that a) help teams win games, and b) make good coaches. I thought the last three years would have or did help shift his philosophy but it doesn't seem he's grown at all.
Adrian's fumble was devastating but he also kept us in it despite other devastating miscues from others. He's got a high ceiling but his environment keeps him down as he struggles mentally too much.
Frustrating but nothing to be done about it right now other than just wait and see.
