Just kicking a dead horse here but this is a critical Rice/Moore distinction:
Look at this route - he doesn't **** around foot firing to try to get a clean release. He doesn't do anything cute to create separation. He goes DIRECTLY at his man knowing how fast he needs to get into the route. DB tries to get physical and Rice just bodies through him; simply out-physicals him to get that little bit of inside leverage.
More critically he gets it EXACTLY where he needs to get it. Not a yard early, not a yard late. Not too deep and not too shallow. He stays on his route, gets a foot of separation right when it's expected and creates a lane for Mahomes to fire a dart into.
THAT'S what Moore doesn't do. That's why I say those 'yards of separation' stat don't mean dick. Because a foot of separation on this play meant everything and it was truly all that was needed.
It wasn't THAT he got separation, it was
when and where he got it that sets him apart from Moore.
He simply knows what he needs to do out there to be a part of the progression. All too often I'm not seeing that from Moore. I suspect he'd have seen the DB lining up over top of him and tried to foot fire then juke outside before cutting inside and by then the safeties will have crashed down into that hole and Mahomes would've moved onto the next guy.
Wanna know why Rice is getting targets and Moore isn't? That play is your answer.
