When I would go back and watch the film Vonn Bell was always in position. He’s playing much better this year. Better than Williams.

Exactly. Being "in position" is one of the main grading factors in the PFF grading system. If the defense is calling plays away from a player's proper position you are not, as a fan, going to notice that player. Or if his position is to force a play in a certain direction you are also not going to see the player.

When all players are doing their job only two or three may be involved in the television cropped shot.
