Offense needs to play like against Tampa with Bengals weak defense. Something like 35-40 might be needed.
Lamar looked bad last week and 5 turnovers led to Ravens being -4. As long as Bills break at least even on turnovers, it should be OK.
But I've seen that called regularly. If he hit him with a shoulder, that's different. If that's the rule, plaintiffs' lawyers will have lots of fun if intentional or reckless head-to-head contact is just fine.
