To me they had to run since the OL wasn't going to give your QB any real time to throw. I would say the OL is limiting on what we can do instead. If it wasn't then Wentz would have been inserted back in after 4 weeks of being out. Dak came back after his injury. To me that is the bigger tell who is limiting the QB.
Taylor has allowed the OL to be a little better by buying more time with his legs like Jay Gruden said. So in turn Taylor is somewhat helping in these wins because of his scrambling abilities, taking a hit while standing tall in the pocket, taking less sacks and not make too many mistakes. This is helping the team to get into a position to win games along with a strong running game. Taylor is not the only reason but he is still a factor than some think he isn't at all. The way the team is playing shows that.
As for "saved our season" - I think the jury is still out on that. If we don't get into the playoffs then all this is just moot anyway. But as of right now Taylor has made us relevant with enough of his "moxie" to keep the flame going. But, we will know more after the bye week and see what the coaches feel and think who is going to be savior to once all hopes lost season.
