Do what you want with this.
So CK improved and Ertz is getting worse.
Congratulations, you win the "idiot of the week" award.
On the totals, other than the rushing TD's and Yards per passing attempts, everything else is almost similar.
And you can't sit here and tell me that he's not going to get better in year 2. It has been well established that starting QB's from year 1 to year 2 has improved across the board.
This will be no different, and expectations should be 9+ wins next year.
