On the topic of moving up:
Teams trading up in the top-15 since 2007: (earliest year Wikipedia has direct links to the trades)
2007:
Sharks trade 13th, 44th and next year's 3rdto St. Louis for 9th.
In actuality, the Sharks got Logan Couture for Lars Eller and two nobodies - Franchise altering move by the Sharks.
2008:
Leafs trade 7th, a 2nd and a 3rd to the Islanders for 5th. Islanders then flip that and a 2nd rounder for 9th, to the Predators.
In actuality, Luke Shenn, Colin Wilson and Josh Bailey moved places - Pretty much a nothing move, until Josh Bailey decided to kick ass a decade later.
Sabres flip 13th and next year's 3rd to the Kings for 12th.
In actuality, the Sabres got Tyler Myers for garbage - Sabres suck, but Myers was a great addition.
Senators trade 18th and next year's 3rd for 15th.
In actuality, the Senators got Erik Karlsson for garbage and garbage - If the Preds had Karlsson, there'd be no reason for the rest of the league to play...
