I really do think he's immature emotionally. Getting jacked up for a pre-season game (his words) was a huge red flag for me. Doesn't mean he can't be good, it just means he needs a lot of seasoning.
As far at 6th goes... pump the brakes. Penix threw for 11 yards more, a 93 rating and lost. He's a solid incomplete. I'll grant that both guys looked good last night, Williams threw for a record breaking 210 yards in a loss, while McCarthy set the world on fire with 143. Nix won, so there's that, but he threw for for a huge day; 176 yards, with a TD and a pair of picks. Daniels also won, and has so far been the brightest of them all, so I am not going throw shade on him.
My point is that 4 of the other 5 didn't necessarily have better days, and it's far from decided that Drake is sixth. He did, however, suck in the second half and hasn't had any level of success compared to Nix and Daniels. Both have some playoff pelts, and Drake just has playoff ticket stubs. So do the other guys.
It's one game with a new staff. One. Game.
