There is no question. Unless Tannehill is injured, Tannehill is the starter.
Agreed, part of me likes the infusion Brock injected into the game yesterday, but again, he's a backup and it showed with that nearly pick-6 he had in the 3rd Q.
Props though to Brock staying with it and keeping the players engaged, especially I heard the comments he made to Drake after the fumble "saying that Chicago was gonna miss the FG and he needed Drake and his swag" when they got the ball back.
Brock's arm was not as strong as I had imagine either. The deep INT he threw before half showed, as he should have put that ball to the outside where only Parker could have gotten it.
All in all, he came in, did his job and got the win. Good for him and the team.
The one thing I will say and it's obvious, regardless if your a Tannehill defender or not, he went through his reads and made throws to WRs that RT usually doesn't do. That's my BIGGEST knock on RT, that he doesn't make reads quick enough and locks on a WR.
If he corrects that issue, he literally would elevate his game to the next level. Until then, he is what he is.
