Two of my favorite plays today involved Witten ..
The first one was when Dak rolled out and Witten was on a short out route. In years past (likely due to Linehan's offense) he would just slow down as he got closer to the sideline to provide Dak with an option if nothing else was available. Instead, for the first time in years, he turned and ran up the field and Dak threw a perfect pass for a long gain. The reason Witten's YAC have been lower in recent years is that he would (or the offense called for him to) turn and sit on a lot of routes which makes it easy for the defensive backs to close and tackle. While I don't hope to see him running long post routes, it's nice that the defense will now have to respect both the turn-back-and-sit and the turn-up-and-go options for him as it will make the defensive backs a little more hesitant than they usually are when he's in front of them.
The other play was the one where Dak rolled out and Witten cleared the lane as the defense stayed with him. The old Dak would have seriously considered forcing that ball to Witten, but he instead pump-faked and ran into the end zone.
I am glad Moore and Dak are not making Witten a primary focus given the other talent on the offense, but it's nice to see Witten expanding his normal repertoire to help this team when needed.
