Once you get your 2 RBs in the first 2 rounds, you certainly don't have to get another RB in the 3rd. I would always take a WR in the 3rd round. Some might say you should get a QB, but I think the earliest you should think about QB is the 4th round, and more likely wait until the 5th or 6th for your QB. You might be able to get a better WR than Housh in the 3rd, I got Holt in the 3rd in my 14 team league.
