I don't think that makes much sense pittbull. Starting in preseason and continuing through the San Diego game DD was THE cutback guy. Every time he came into the game the offense took on a completely different look and it was like "instant running game". The other backs never made the cutbacks but DD always found the seam and popped through for good yardage. Hollings was seemingly incapable of spotting the opening on the backside and Wells was simply too slow to the hole.
Starting in Detroit DD stopped running like that. I believe the answer is simply "four fumbles" and their effect on his game. He's not looking for the cracks like he was before. He's looking to make sure the ball doesn't pop out which in turn leads to him being about ten times less effective. In the meantime the other backs (or should I be saying "back" since Hollings has been out too) have started to get the hang of things.
DD will have a better second half of the season than he did first half and when our running game comes back around the Texans will find a whole other "gear" to shift into. They're good now but by the end of the season they'll be damned good.
Fitz makes bad decisions. That's not going to change.
