Err... Hoyer is 16-21, Brissett is 3-13. Not sure you can say that with any confidence.
That "checked out" Texans team made the playoffs. And Brissett played against the Bills with a broken thumb on his throwing hand. That's pretty laudable all by itself.
Let's make no bones about it. That Colts team was BAD. B-A-D BAD. Andrew Luck had failed to coax a winning record out of this team the previous year.
I followed them last year and they specialized in one thing and one thing only -- 4th quarter meltdowns. Brissett isn't a great QB, he can't cover for a team that plays 45 minutes and throws in the towel. They melted down at least 6 times that season to lose games that Brissett had given them a chance to win. If that Colts team had been able to take care of business for a full 60 minutes, Brissett goes 7-9 or even 8-8. Even if they'd won half the games they'd had a lead in the 4th quarter, that's a 6-10 or 7-11 team.
They didn't have an offensive line worth a damn, they didn't have a running game, and yet Brissett managed to give the Colts a fighting chance far more often than not. For a guy who doesn't have a top end skillset, that's pretty damn impressive.
