Niemann For Blanks

[Padres Fan]

I am in a 11 team ESPN Roto scoring

Scoring: Runs/HR/RBI/SB/AVG/OPS
Scoring: K/QS/W/ERA/WHIP/SVHD

My SP's have been good and I think I finally caught up on the Saves and Holds, but my offense has been inconsitent and weak so far, Another player in my league is a huge Rays fan, and seems to really want Price or Garza,but has been offering Blanks straight up, should I counter with Niemann for Blanks instead, his last trade was me Cruz for his BJ Upton and Blanks, which I can't do.

Since you are a self-professed Padres fan, why are you even considering Niemann for Blanks? What are you going to do if Blanks is sent down or continues to ride the pine on a semi-regular basis? If you sell Niemann, you sell high, not low.
