2ppr for TE's, when is too early to get gronk?

PPR league but 2PPR for TE’s. I have the 7th pick and am seriously considering taking Gronk with that first pick because I don’t think he will make it back to me in the second. What do you think? Worth it or should I pick best available and settle for kelce/ertz in the second?

I still wait til the 2nd personally. You can still get someone like Walker later on too
