It's all academic now, but Buch didn't score the 70 until after he left here, which was after the Eichel trade. As good as his 48 in 54 (0.88 ppg) season was, there were questions at the time as to how much of that was due to CK-Mika, and just how sustainable it all was.
Strome I don't think really had value at all; so you had Tuch who was a year younger, had just gone 33 in 44 (0.75ppg) and 1st round pedigree (which seems to matter more than it should) plus a young former 1st rounder in Krebs who at the time had a fair bit of upside and the picks
Buch was the best player of the group but the gap to Tuch wasn't been as that high at the time and Krebs would have been more attractive than Strome, plus our picks would have likely been later in the rounds or we would have had to add more
IMO Buffalo was right in taking the Vegas deal over ours, despite how it all turned out in the end
