Trade Talk - Gronk?

I have the Gronk owner asking me for Diggs. Is this trade fair?

I give up Diggs and Philip Lindsay (Or Marshawn Lynch)

Get Gronk and Brandin Cooks.

Thoughts? He offered Marvin Jones and Gronk straight up for Diggs at first and I don’t think I want to bite on that. I have Keenan Allen at WR and Jordan Reed at TE. 12 team PPR.

My team:
K Allen
S Diggs
C Davis
S Watkins
C Godwin
A Kamara (bye)
M Ingram (bye)
D Freeman
M Lynch
P Lindsay
K Drake
J Reed
