According to Seidel they didn't do it because they didn't think Yakemchuk would fall to 7, which is amusing considering he was largely expected to go 10-14.
The Sens scouting staff clearly thinks the rest of the league are idiots. Their lists routinely differ from the consensus to an absurd degree. No idea how they come up with the idea that Beaudoin is deserving of a top 10 selection, and I'm someone who likes him enough to have voted for him in the HF Mock Draft when we still had pick 25.
There's been zero self-reflection after picking Boucher top 10 and Thomson top 20. They still think they are the smartest people in the room even though it's been proved otherwise at this point.
Also I don't hate Yakemchuk. I thought he'd be a fine pick in the 13-15 range. Just preferred several other players available at 7. Sens staff picking him 7th did nothing to change my mind considering I watched Yakemchuk a ton this year, just like it didn't when I criticized the Boucher/Thomson picks when they were made.
