David Njoku (Cleveland Browns): Njoku is a very athletic tight end who had a decent rookie year despite being on the worst team in football. Whoever is throwing to him in 2018, whether it’s Tyrod Taylor or Baker Mayfield, will be an upgrade over DeShone Kizer. Njoku is a sleeper headed into 2018.
Vernon Davis (Washington Redskins): Davis is the oldest player on this list, but I still think he will be a solid tight end for Washington in 2018. Alex Smith loves throwing to his tight ends, and he will love being reunited with Davis even more.
George Kittle (San Francisco 49ers): Kittle has a lot of potential and I think he could breakout this year with Jimmy Garoppolo throwing to him for an entire season. The Niners are a sleeper team headed into 2018, and Kittle will be a difference-maker in their offense.
Austin Seferian-Jenkins (Jacksonville Jaguars): Seferian-Jenkins had a breakout season last year in New York. Expect him to build on that performance this year. Blake Bortles should target him a lot, and there is five-plus touchdown potential with him this year.
Jack Doyle (Indianapolis Colts): Doyle is a good tight end, and would be even better with a healthy Andrew Luck throwing to him. If Luck isn’t healthy again in 2018, expect him to still be a top receiver in Indy’s offense.
