I would agree that it's stupid to hype up recruits until they produce, but every WR I listed, besides Kurtz, has contributed at least some in their time at BYU.
I really liked what I saw from Juergens (minus the fumbles) and Pearson (before he got injured). Juergens is a great option at the slot WR postion, and I think Pearson will be at least as good as Ashworth.
