I imagine it along the lines of how defender lock works in NCAA and how I figure defense is played in Backbreaker from that view, though I have never played that game. The funny thing is, that I have put way more thought into this than necessary so here goes. lol
The view would work the same way for defenders with the zoom/viewing radius being dictated by AWR and what the player is doing. For example Ray Lewis would have a wide view when playing defense but if he was to intercept a pass, his view would become zoomed in/smaller as a returner, maybe being based on BCV at that point. Same thing for CPU players that intercept passes or that have to become blockers after a turnover and vice versa for User or CPU offenses players that have to become tacklers, with their vision/view being dependent on how skilled they are at whatever they are currently attempting.
It would add another layer of difference between great CB's that are dangerous at returning INT's, great kick/punt returners, skilled special team blockers/tacklers, all elite BCV players when getting the ball in their hands, great pulling Olineman vs great zone blockers, good run blockers vs good pass blockers, etc. It would make a clear distinction between elite players with high AWR at their position along with that same player at a different position with lower AWR and that player at the same position but performing a different action.
So Tom Brady's view dropping back to pass, would differ from his view if pulling the ball down to run, a wily vet like WR Hines Ward would have a wider view for route running than running after the catch and vice versa for a receiver like Devon Hester. Also, a RB with high AWR/pass blocking, low BCV would have wide vision to pick a hole prior to the handoff or for picking up blockers on a pass play but zoomed in/smaller view when carrying the ball and vice versa for a RB with low AWR/poor blocking skills but high BCV.
Evey player would be inherently unique whether CPU or User controlled and there would be actual User skilled involved in utilizing lesser players. The possibilities for this type system are seemingly endless, imo. lol
