Oline communication seemed really bad but situational awareness seemed really awful as well.
It is as though the Oline was only aware of their own responsibilities and had no idea what backfield protection they were getting. On one play Hurst gives up a sack because he leaves his man to pickup a late outside pressure that Kamara can easily chip and as Hurst kicks out he runs over Kamara. The guy he tried to hand off to Peat (who was already busy) got the easy sack.
