I'm opposed to making any trades to move up, unless it's in later rounds and for minor pieces. This team doesn't have the tradeable assets – ie, desired by other teams but not fitting the Flyers going forward – to make a major move and grab another 1st or even early 2nd. That window of opportunity was shut by Brière's head at practice.
Choose wisely with the picks they have and restock the Phantoms. There are too many case studies of early-round busts and late-round gems to try to move around with players who are already high-ceiling and the property of the Flyers.
