When the Philadelphia Flyers traded Braydon Coburn to the Lightning in March of 2015, the biggest return was the first round pick. Tampa Bay was gearing up for a Cup run and the Flyers were rebuilding so the trade made sense. The Flyers managed to get a third round pick as well and after some more trading at the draft, the first rounder they acquired from the Lightning turned into Travis Konecny.
By itself, that looks like a pretty darn good trade for Ron Hextall and the Flyers. But Tampa also sent over defenseman Radko Gudas to complete the trade.
