Only choose AD if the player seems actively involved in defensive headers.

My DL/DC with AD seemed good with headers before the SA and seems good with headers with it.

Is he better with the SA than he was without? Was it worth the sp?
When I see a player stat count on Defensive Headers I'll tell you.

He used to play DC but now is more used as DL.

PS. I've not tried DW, I prefer to feed them up on pies.
