I think you're too low on Hill. Preseason will give us a better idea though.
There are more Zach Sudfelds than Julius Thomases. I wouldn't want to put Josh Hill ahead of someone like Fleener who has similar athleticism, a similarly great QB (but much younger), and was already a top 8 fantasy TE last year.
Actually, I'm probably underrating Fleener.
Actually, I think I was underrating Fleener by a lot.
If I knew for a fact that Indy was going to re-sign Fleener long-term and let Allen go after this year, then I'd put Fleener on tier 5, with Cameron, Reed, Green, etc. Probably even at the top of that tier. Luck's TE, relatively tall & athletic, early 2nd rounder, with a 51/774/8 season in his 3rd year. Red zone threat on a team that scores a lot and apparently has a thing for tiny WRs.
If I knew that Fleener would leave Indy and sign elsewhere next year, then I think I'd have him on tier 7, near where he is now. In terms of talent, I think he's more like Rudolph than like Donnell or Housler. And I think I'd also have him on tier 7 if I knew that Fleener and Allen would both re-sign in Indy.
Combine those 3 scenarios, with appropriate weightings, and Fleener pretty clearly belongs a tier higher. Let's say Allen at 13 (with a slight increase in value based on similar reasoning), Fleener at 14, and Amaro down to 15.
