The more I think about this the more I think I would have converted one of the jumbo WR's to this position. This is a valuable scholarship in 2018.
There's a great chance that the 2018 roster will only have Kmet, Wright, and Takacs. Adding Tremble will keep the depth at a semi healthy level; so, using a scholarship on him is valuable too. I'm not a fan of using a jumbo WR for his position. ESB is too skinny, Claypool has the strength and athleticism to be a terrible mismatch out wide, and Boykin showed a lot of promise this spring at receiver.
