No. I actually have thrown 11 TDs and 6INTs through 4 games, and I have no problem with offensive turnovers... It's the fact that my defense is 32nd in the league with an 86 or 87 rating. It's probably the most physically gifted and talented "Bend but don't break" defense the league has ever seen at this point. I have 5 starters on defense rated over 90 and only 3 rated below an 86 and no one below 81. My DEs are 94 and 91 and I get 3-4 sacks per game with them and sending some safety and CB blitzes.
The problem is that my CBs can cause turnovers from time to time, but it seems to be either INT or a completion, no actual good coverage while the CPU can get some good honest coverage against me.
