I am a HUGE Tyrod Taylor fan. But, I have to agree on this. The line was bad, at least very inconsistent—which, I guess, is bad.
Nonetheless, TT did them no favors, especially in that abysmal first half. I however, think the blame has to be shared by the Offensive Coaches. Remember when we were all over Hackett and Company about telling EJ not to scramble, to be cautious in using his feet? I think the same thing has happened to TT. All along the questions has been, "can he stand in the pocket and make NFL passes?" The answer is No!, at least, not on a regular basis.
So here's a better question: "Should he try to do that?" Again, the answer is: No! That is not his game, and he will not be successful at it. It was almost like he was told not to run in the first half: "Whatever you do, stand there and go through all your progressions."
Compare how he played in the second half with the first. He was moving, when he scramble, it was away from pressure, and sometimes for positive plays when there was nothing downfield. And when he did make big throws, with the exception of Watkins TD, they were all when he was on the move. Now, he also threw an interception then, but the good out weighs the bad in this exchange.
Here's the point: TT is an athlete. Take advantage of his athleticism. He is not, nor should he be, a prototypical NFL QB. He is an athlete, let his use his feet, his quickness, and his rocket of an arm, to beat teams. Add to that, he has a suspect line that can not hold a pocket, and it is even more of a case for using his athleticism. Compare the first half with the second, and you see the results.
