There's plenty of depth and talent available.
If we can't find someone from 2018's freshman class to step up and seize a starting WR position, then there's something seriously wrong with our player development.
Claypool is ready to be the #1, go-to WR position. He's now a seasoned, experienced veteran who understands the game.
I would have to guess that someone between Austin, Keys, and Lenzy, should be able to prove themselves, now that they've had some experience, and will have had another off-season of S&C, training, etc.
