Trading for Gronk

[scottybo 0]

In a full point dynasty auction ($100 salary cap) ppr, would you trade 2 of the following for Gronk ($15).

 

Sterling Shepard ($3)

Jamaal Williams ($5)

Corey Davis ($11)

Alex Collins ($7)

 

My Team

 

QB - Rivers - ($4), L Jackson ($1)

RB - David Johnson ($9), Jordan Howard ($10), Alex Collins ($7), Jamal Williams ($5), Aaron Jones ($4), James Connor ($1)

WR - OBJ ($13), Amari Cooper ($21), JuJu Smith Shuster ($7), Corey Davis ($11), Shepard ($3)

TE - Kittle ($3)

 

So definitely weak at TE so Gronk would be a big upgrade. But his health scares me. So giving up 2 potential long term keepers for a one year rental in a dynasty could be risky. Thoughts?
