Jettas, Breece, K9 for Rico Dowdle and Rashee Rice?

Hey all, back with a trade offered my way. I was initially trying to grab Rico and Jordan Mason for Jordan Addison, Ricky Pearsall, and K9, but then given this offer in rebuttal.

The 8-1 roster:

QB: Mahomes, Goff

RB: Cook, Breece, Rhamandre Stevenson, K9, Bam Knight

WR: Jettas, Pittman, Addison, Pearsall, Tre Tucker, Kupp

TE: McBride

I’m fairly confident in Jettas for Rashee, more confident in Rashee QB situation, although Vikings have a pretty good ROS. Biggest uncertainty is Breece for Rico. Rico only recently went into RB1 role and I just don’t know what the ROS has in store for him. K9 is worthless to me because of Charbs
