There are turnovers that are forced and are good plays by the defense. Like the Grant fumble, someone came from out of his vision and punched the ball out. Yes Grant could have done more but that fumble was a great play by the defense.
Then there are giveaways. Either just plain unforced drops, like the 2 snaps he dropped, or the snap he called for with the motion man in the way, or the incomplete handoff to Ervin or they are interceptions where the defense was in position to pick it off. Those interceptions weren't great plays, but expected with where the ball was thrown.
Turnovers happen, but unforced giveaways should not. The way Sims has just given the ball away is shocking.
