Blackmon/Ryu for Kershaw/Muncy?

In a 4x4 rotisserie league. NL-only.

I send Blackmon/Ryu and receive Kershaw/Muncy.

I like Blackmon better than Muncy, but my infield could use a little help. I would slot in Muncy at 3B (currently I have Mark Reynolds for a $1). But, I have Lowrie as well that could play 3B, and he should come off the DL soon.

I REALLY like Ryu so far, but maybe a good chance to sell high on him?

I would keep Blackmon/Ryu here and try to find a different way to upgrade your MI
