This is the dilemma.
It's not that we aren't worried about RB depth- I am very worried, and we need another body at the least. And it's very likely the RB room overall takes a step back without Martinez, Allen and CJ.
But nobody is going to sell a proven back without losing one of our current Top 2 backs. So the depth problem won't get solved that way, and we end up spending more.
I like
@Memnon's idea of swiping a highly recruited back who hasn't played that much. That's more affordable and less likely to shake up the room.
