Gronk was top TE last year, but 8 RBs put up more points, so you have that to consider.But there is only one first round TE. So of course you can't get a replacement at that level.
I get what you're saying, but it ONLY counts for injury. A RB you pick first can just not be a top 10 option, it happens (McCoy). That is not happening with Gronk. If he plays, you own the best TE bar none.
So your safety is injury safety....which is nearly impossible to predict.
My safety is production projections and Gronk is the absolute safest in that scenario.
And there are WAY, WAY more late rounders at RB/WR that can jump into the top 10 (non-QB) out of nowhere. Not a chance at TE.
