Imo, TD's decision making and lack of success on 1st and 2nd down were huge factors in the sack totals. There were way too many 3rd and longs where the opponent's defense just pinned back their ears.No question his experience and blocking ability was missed. There was a lot of contributing factors. I think Tommy had some responsibility, the OL a lot, the WRs had some and the OC played a part in the meltdown too.
I am saying that if you have a QB who can make plays outside the pocket, it helps mitigate issues with pass blocking. I don't think Dillon will ever be close to the playmaker that Eric was, but it looks like he can make throws and extend plays running to his left or his right. That could be a big deal for this offense some day.
Word is that he struggled with the "playbook" and making the correct reads at the LOS. It's the main reason the offense played at a much slower pace than the year before.
