I don't think "blasted" is an accurate description, "disappointed" would be closer to the truth.
Bonk is a 2nd pair guy, which is fine where he was drafted, he's going to be a smart, physical (probably end up 6'2 220), CYA RHD who can pair with Andrae, York or Sanheim, or if they draft an offense first LHD this summer. If Andrae/Bonk is a solid top 4 line, they're in pretty good shape with Seeler/Drysdale as your 3rd pair.
I don't know how you project Jett, he's a season behind draft peers like Catton b/c he only played in the top 6 at 17. Playing for Guelph suppresses his scoring and his development, on say London, he's probably a 1.5+ ppg center. Problem is I don't see Guelph adding much forward talent next season, ideally they'd stash him in the AHL for a season, but that's not allowed.
