Of course it was. He was bad. Were you praising how good he did in the 4th quarter of game one, as you are hating on him now after game 3?
Have some perspective. He is a rookie, in his 3rd NFL game. Did you expect him to not have bad 4th quarters? What are your expectations of him? I honestly want to know.
First, what Murray did vs the Lions was garbage time stats. It is nowhere close to the same situation as the 4th Q of the Panthers game.
I worried about his size pre-draft and how it would affect his willingness to stand in the pocket and take a hit, or take a hit is was unable to get down when he scrambled. So far, he has not seemed willing/able to stare into the face of a blitz and deliver an accurate ball down the field.
I worried about his experience pre-draft. Had he played enough football to know what he was seeing and do the little things it takes to win in the NFL. So far, he has struggled with pocket awareness, knowing when to scramble, and overall game/situational awareness. He takes unnecessary losses running out of bounds instead of throwing the ball away, he runs into sacks, and has struggled in the red zone and on 3rd downs.
I worried about his lack of overcoming adversity. Over his career he has generally had the best personnel on the field. The few times he didn't, Texas A&M and vs Alabama, he struggled. That is what I feel he has done so far in the NFL. He has consistently had equal-to or less-than talent than the teams he has played so far and has zero wins. That is not overcoming adversity, this is being as good as your talent. It is Dak Prescott-esque.
I worry now that Murray is too tight. I think this is why he is a slow starter and why he struggles in pressure situations. It is easier to play freely when you are down and have nothing to lose vs when you are close and have to execute to win.
I felt that Murray was very accurate in college and feel that he has been very accurate in the NFL. Same with his arm strength.
In the end, Kyler is pretty close to what I expected him to be. A good NFL prospect who has a lot of ways to fail and be a bust. Size, experience, and mental toughness (not intelligence, he is smart). If he can overcome those, he should be fine. If he can't, he will be out of the league. That being said, Murray is far from the prospect that people on this board billed him to be.
