Front load on RBs?

Was wondering what people would do if the opportunity came up to draft 3 top RBs in the first 3 rounds instead of balancing with WRs.

For example, would you prefer something like…
CMC, Mixon, Carson, Lockett
CMC, Mixon, Thielen, Lockett

Just curios, given the relative lower depth of RBs, whether drafting 3 top guys early seems like a viable strategy. Assume standard scoring and roster. Thoughts?

I went RB, RB, WR, RB in my draft. Ended up with him Gurley, Bell, Allen, and Jacobs. My following picks resulted in me grabbing Woods, Montgomery, and then snatching up OJ before my buddy could. I drafted 7 in a 10-team standard league though. I personally am not as high on Mixon as some of the other RBs that can be had in the 2nd and 3rd rounds.
