If you are getting 4500 yards, 30 TD's, 5 picks with a 68 rated QB, then the game is severely broken. Why even have ratings.
Things I'd like to see in M25/14.
The OP's suggestion of bringing back an Owner Mode into CC with all the previously removed features added back in.
On option to have a very realistic, potential based progression system that models how progression actually occurs in the real world. Not mimic every players real world progression, but have a progression system that uses a real world model, using real world variable.
Make the game customizable and completely editable.
I like a lot of the OP's post except for the progression stuff.
