lol, no, you are the one full of it. A receiver catches the ball in full stride without hesitating or slowing down, even by your own admission, and you are blaming the throw for him not getting a first down.
And, again, it was a short throw just beyond the line of scrimmage. A QB can float a soft, high arcing pass way ahead of a receiver and make him go get it that close to the line of scrimmage, with all the congestion around the line of scrimmage. That would be begging for an INT. On a short throw you have to get him the ball and let him run. Again, it wasn't a perfect throw, but it wasn't the abomination you suggest, and Lamb was able to catch in full stride just as if it were perfect. The defender did a great job working through traffic to make the play.
Sometimes you have to just accept that the defense makes a good play.
