Says Pro Football Focus:

TIER 2 – STILL ELITE Zach Ertz, EAGLES George Kittle, San Francisco 49ers

Ertz and Kittle don’t quite match Travis Kelce for fantasy purposes, but they aren’t that far off either.

Ertz is coming off a massive 116-catch season. That floor is very appealing, but he doesn’t have Kelce’s ceiling. Additionally, we could see a bit more of Dallas Goedert in the Eagles offense this year.

Kittle is coming off a breakout 2018 season with an enormous 15.6 yards per catch. His ceiling is still massive, but regression in efficiency could depress his fantasy numbers slightly this year. Either way, these two are studs who will likely be drafted within the first 24 picks this year.
