Look, when you are arguing about who is best at QB2, you are always going to be looking at a tough season.
Right now, I believe TH7 gives us our best chance to win. Especially with this beat up O-line.
I am not sure I believe that Seimien is as bad as this O-line made him look, but I am fairly confident that the O-line would make Book look awful.
This isn't a "Taysom against the world" post - it is a "Taysom against our situation" post. There is just not a better option right now.
