Draft question - crazy point sytem

Quick question regarding a draft I have tomorrow. 12 team league. The commish decided to make the point system a little crazy:
1 pt per yard for both RB’s and WR’s
PPR
1 pt per carry for RB’s
1 pt per completion for QB’s / 6 pts for TD’s.

So in a nutshell, the RB position is very important with this scoring.
Question - I have the 1st pick now…should I trade someone for the 5th??? I feel like I will have more options for RB’s in the middle, but every mock I’ve done so far, I have a better lineup at the 1st pick.
ANY ADVICE APPRECIATED!!
