Just for reference, out of Goff's seven seasons, he's putting up his:
3rd best season by QB Rating
2nd best season by QBR
3rd best by yards per attempt
3rd best by INT%
3rd best by TD%
3rd best by completion percentage
3rd worst yards per game
3rd best sack%
So for the most part, he is what he is; a solid starting QB who's going to need to be replaced if his team wants to have a real shot at making/winning the superbowl. Luckily for Goff though, he plays for the Lions, so there's no need to worry about that.
