Well, I'd look at it this way Gronk is so far above other TEs that you're unlikely to get close to his numbers from another TE. But I think I have to go Newton and hope I get my Gronk or Antonio Brown or the ilk in the 1st round.
That's what I'm thinking too. It is a PPR league, so even an injured Charles is very attractive in the 8th. But, this is also his 2nd blown ACL, which worries me.
I was certain I'd keep Gronk until a couple weeks ago. Now, like you say, I keep Cam and hope that Gronk is there when I have my first pick.
This year though, guys like Greg Olsen, Travis Kelce, and, to an extent, Delanie Walker and Jimmy Graham have been pretty stellar in PPR leagues at TE. The gap between Gronk and everyone else isn't AS noticeable as it was a couple years ago. He's still far and away the best out there, but I agree with the others - the fact that you'd lose your first round pick kinda sucks. Cam would be my pick - I think he turned a major corner this year and is a solid MVP candidate.
