Well, good news, the Bears can bring in a ton of UDFA RBs and have a running back by committee approach, getting close to the same results as they would with drafted RBs.
Every once in a while the RB room would get a "Johnson, report to the running game coordinator ... and bring your playbook." to which RB Johnson would ask, "Am I being cut?".
The coach would then say, "No, you are not going to be cut" and then he would whisper under his breath, 'Roman is going to swallow you whole, like a huge snake would do. No need for cuts'.
