Tua is done for at least 8 weeks, and very quite possibly for his career.
It's between us and the Jets, but I agree with you that it's too early to write them off. Hopefully their Week 1 is a sign of further things to come and we can pull ahead in the division as early as possible. The rest of (or at least most) of our division falling apart and being truly bottom of the barrel in the league could go a really, really long way to getting the top seed.
