20 is a ton agreed but this one I think won't be close and I'll tell you why.
Jax #1 Qb is out. Granted hes about the same as their 1 but their best WR (Blackmon ) is suspended. Jones Drew could be out and then add in that they are yet to score a TD this season.
To add fuel to the fire they are headed to the loudest stadium and face the leagues best defense.
My O/U for them crossing the 50 is 2.5 times
