There were two different plays and people seem to be getting them confused. The one where the number is not clear he didnt get trucked. He tried to tackle high didn't wrap up and bounced off.
Later where AOA's number was clear it was again a screen to that side and in his pursuit, he tried to just run past the blocker instead of engaging the block, the blocker lined him up and knocked him on his ***.
I am guessing the latter is what people are talking about when they talk about awareness because I did not see him iss an assignment which is more than what i can say for the other safeties.
I would be morec oncerened if he hadn't gotten back up after that shot he took and continued to chase the play.
Its pretty obvious from watching him that he is green as grass but I guarantee you ont he next screen he sees to his side he won't just ignore the blocker to try to run to the ball again.
Sendejo is mediocre of footspeed and is more fiesty than physical and there is a difference. He drags ball carriers to the ground, he doesn't just knock them over.
