I get where people are coming from with the sentiment that Ewers needs to play better. I also completely agree that I think that the OLine, Sark, and some WR issues are not making things easier (In particular see Klatt's analysis post-GA). That being said, the team is 7-1. Ewers is not playing his best post-injury obviously and he only looked great v. Michigan. There is no way Sark makes the change if Ewers plays like he did v. Vandy. Not because he gives a shit about his QB guru bullshit. But because like others have said, if he has to go to Manning - then that feels more like a permanent solution than a temporary one. IMHO Ewers stays in until he plays himself out of an SEC Championship game or National Championship playoff spot. That could happen mid-game against Florida, Kentucky or Arkansas if he Sark feels he is shitting the bed. I just don't think it happens in those three games.
Finally, I am not willing to believe the person who started Tua over Jalen Hurts is somehow not capable of pulling a similar move here.
