Uncertain if this is a bug or a misread on my part.

Headline: All offensive players have identical play familiarity

Reproduction: select player from roster, head to their full stats page ("view" from the pop-up). Head into OFF PLAYS, select play (in this example HB Flare in the 113).

Every offensive player, regardless of experience, time with team, starter or backup has the exact same familiarity.

Am I misreading the information?
Is that the average knowledge the offense has? Is that the knowledge the coordinator/HC has? (If so, what impact does this have?)
Is it just a display bug, and players are learning plays according to their exposure to them and scouting of them?

Basically, what gives?
