I think its because the talent at D3 isn't good enough to keep turnovers low against the press at D3, I could care less for FCP so I made my D2 transition quickly after 1 season... Once in D2 I have faced maybe 1 team with FCP halfway through my season... Offense is still a preference but definitly FCP at D3 is most used and probably "best" defense at D3 because that talent can't keep up with it on that level
