It's fair to assume that the tight end usage for the Chargers will start to favor Hunter Henry more and more as Antonio Gates continues to age, but Gates played 14 games in 2016 and drew 93 targets. Henry played 15 games and saw 53 targets.
People forget that.
Henry's ADP puts him as the TE10 (9.06) in 12-team PPR draft (Gates doesn't have an ADP). Henry finished as the TE19 in 2016 despite the low volume (thanks to eight touchdowns).
Of the 372 tight ends with at least 35 catches since 2000 (Henry had 36), Henry's Reception NEP per catch ranked 19th-highest last season. Even if he can keep his efficiency on par with Rob Gronkowski or Gates himself, Henry will need a big boost in volume to live up to his price tag.
For a guy who played more than 60% of the team's snaps in 5 of 15 games and more than 70% in just 3 of 15 games, a ninth-round ADP is pretty steep.
