Those face shields on skill players have always bothered me.
On one hand, particularly for backs, the face shield can mask the defense where the runner is seeing the hole developing. On the other, the subtle looks between pass catchers and the QB have to be degraded.
Kamara seems to have no issues. So, maybe I'm wrong.
Again, I think the combination of the mask n lighting can affect some receivers, esp on high, deep passes. Another factor could b experience, as vet players are used to em n probably more comfortable with em than younger players. Just a thought.
AK gets VERY few deep passes, but as a vet, it probably doesn’t affect him anyway, But like you said, it’s an advantage for him, esp on those short/intermediate option routes.
