Why should I take George Washington seriousely. Heck at well over 200 years old, you can't see, and you have senility. Why am I even responding. Go ask Ben for some bi-focals. Maybe you'll be able to see the plays better.
Now, as to the pertinent question, here is the answer. Peek cannot play the run. He can't contain on the outside, and cannot shed the blocker to make a tackle on the RB turning the corner. If you can't play the run, you can't play in a Caper's 3-4. Babin has held containment very well imo, especially for a rookie learning a new position. If you expected Babin to play like a well seasoned Keving Greene in his very first season learning a new position, then your expections need to get rearranged in your cerebial vortex. Go ask Adams or Madison what that means.
