I think the throw at Moore referenced was on purpose. Could he have gotten more yards if it was out front and he caught it? Yes, but no receiver was catching the ball away from his body all game.
Even the throw here... was it really that bad of a ball? Went right through the WR's hands. He could have put it where he did to give the WR a chance to use his body instead of trying to lead him.
And I'm not blaming Goodwin, either. It's physics. If the ball is heavier than normal, it's harder to catch. Force equals mass times acceleration. Increase the mass and that's a lot more force. There's a reason people don't try to catch cannonballs. Obviously, there is a different degree of mass involved there, but the principle remains.
I talked about muscle memory and the ball's weight earlier, but there could also have been a mental adjustment required if he's trying not to lead his receivers and rather trying to put it on them where they can use their bodies to catch it more.
