I just think in today's game, paying a RB a shit ton of money, in a passing era, is just stupid. It's the position that traditionally gets hit the hardest, the most often, and the return on the investment/longevity is the worst of all positions in the sport. RB's grow on trees. I'd draft 1 or 2 every few years and just keep cycle going, and would never spend a 1st on one.
If you have a good OL, your RB can be average and you can get by with really good results. Pay/keep your fatties, they last longer (unless youre Mitch Morse)
