I knew someone would take the long hanging fruit here and spin this as if I am saying the guy is Barry.
I am merely pointing out a back that is hailed as the greatest of all time was 5-8.
There have been several short backs that have had success in this league.
If he was 5-9 instead of 5-8, this would barely be getting talked about.
5-8 for a back of his caliber is a non-factor. We aren’t asking him to do anything with his height (catch passes in traffic, see over the OL to complete passes, etc.).
