Exactly.
The problem is there are a lot of RBs. Some star RBs didn’t even start on their college teams. Look at the Bills. I believe Cook and Harris didn’t even start in college but became starters in the NFL. Alabama and Georgia have had multiple allpro RBs on the same teams.
There are just so many good RBs available.
Becoming UFA earlier will help a few RBs but it’s not changing anything. We’ve seen Zeke and Gurley sign deals at 23-24 years old. Those contracts weren’t good for the teams.
Edit: Harris did start. Josh Jacobs, Najee Harris, and Brian Robinson were his backups. Alabama always seems to have 2-3 NFL RBs every year. Point remains, there’s always RBs.
