I really like this take. I'd say:
The Good - Great depth and competition. No matter how you rank them, there's probably not that much fall off from our #1 to #4 RB. We can absorb injuries without missing a beat and they should push each other to get better.
The Bad - We still don't have 1 special/elite RB (yet). This is more a "sum of it's parts" type backfield. You gain & lose something when each RB is on the field. When everyone's healthy, it's gonna be hard to manage/distribute carries. Unless a RB really steps up & separates themselves, which is what I hope happens.
I'm assuming Chaney will sit out Spring - so I look forward to Parrish & Thad pushing for Knighton's #1 spot.
