10 team Snake - Looking for advice

[TitsMcGahee]

I'm in a 10 team snake league coming up here. The league format is:
Passing: 25 yds/1 pt, 4 pts TD
Rushing/recieving: 10 yds/1 pt 6 pts TD
positions:
QB
RB
RB
WR
WR
Rb/WR Flex
TE
K
Def

With that being said, do you think my first 3 picks should be RB, RB, RB which I am considering. Or potentially going with RB, TE (Graham), RB. Or in the scenario I could land Calvin Johnson potentially in the first, grab him and then 2 RBs and wait on a TE? We don't know our position until the live draft room which pretty much sucks so I'm just trying to cover all scenarios. I'm also viewing this Flex as good potential to fill with a stud RB.
