It'll be a good test of how grown up the team is.
They have to perform well win or lose. If not it looks a lot like 2nd half of last season ending in a round 2 blowout.
The ADR surgery can be very successful if the real source of the problem is the disc and not something that is causing the disc to herniate.
Stable/strong spinal muscles plus no ligament instability make for best result in ADR.
JA will never be the perfect QB like Brady or Montana or Ken Anderson.
But the closer he gets to that level the better chance the Bills have to play in a SB for the 1st time in 27+ yrs.
