Trade Question help

I am thinking about proposing trading Dez Bryant and K. Rudolph for Gronk.

My reason being is that I have 3 minn plays D. Cook, K. Rudolph and S. Diggs. I can’t start all 3.

TE H. Henry was hardly on the field and was out played in snaps and catches on his own team.

So I need a TE

My Wr’s are D. Parker (mia-now with Cutler), D. Bryant, S. Diggs, D. Moncrief, M. Jones So I feel that I have flexibility.

Should I make the trade offer or just scan the free agent market to find a TE?
