RBs for first three picks?

So I’ve never done this before but im considering taking rbs with my first 3 picks. I have the number 2 pick so it would look something like MCcaffrey/kamara, kerryon Johnson/mack, and then damien williams/aaron jones. What do you guys think about this strategy. I usually end up with some variation of Golladay, Anderson, Boyde, or kupp which I think is solid enough considering I’d have such strong starters at rbs and my flex. I’d like to hear opinions though
