12. Darren Waller, Raiders (Sleeper)
Waller may be the definition of a deep sleeper in fantasy drafts. He’s been suspended twice, including a season-long suspension in 2017, for violating the league’s substance-abuse policy. Of course, it’s a lot easier to take a chance on a player with character issues in fantasy football than in actual football. He also has just 18 career receptions and four career starts under his belt.
That being said, Waller is in line to be Oakland’s starting tight end this season with Jared Cook leaving the Raiders during the off-season. He played wide receiver in college, albeit in Georgia Tech’s triple-option offense, so he has the skills to be a pass catcher in the NFL. Waller will likely get the reps he needs to be an impact fantasy tight end, it’s just a matter of him taking advantage of his opportunity. Considering his upside, he’s worth the risk if you can get him in the later rounds.
