Is it PPR?? You have some flexibility at that 5th spot. However, I don't know if I would get overly excited about Gurley as some suggest. He's bust potential IMO given the team he's on with a below average offense. Last year his final 8 games he averaged 3.9 ypc and he plays in one of the tougher divisions of defenses and Rams are 1 dimensional. I'm not big on AP. He's good don't get me wrong, but hes aging and from what I understand if Vikings plan to switch up to the shot gun style offense to give Teddy better looks, it threw AP off last year during that time.
If Julio is available, he is the obvious choice for me, I'm bigger on a more reliable wr. Rbs are too risky with how they have had injuries last couple years, but if it's between Gurley and AP, I'd go with AP.
