Gronk's upside is worth the risk, especially considering that they can't key in on him alone, with everyone healthy in NE's receiving corps and backfield. Gronk will be Gronk in week 1.
I have Gronk and Witten. Gronk's the better TE but I doubt he's gonna play the majority of his snaps. Witten's a solid TE and probably Romo's to go guy other than Bryant. Who should I start?
