The recent trade involving the Devils not only appears lopsided, but is objectively lopsided. The Devils received a player of greater value than they lost, coming out ahead of their trade partner. This might not seem fair, but should be allowed because as long as both teams agree on the trade, it should be seen as fair to the governing body (the league).
Still not sure what impact this will have on Oilers. They are not close to being a playoff team anyway, so I'm not sure any trade they make at this point can be termed "bad", but I do know that this should really help the Devils. Taylor Hall will flourish in an easier conference and with a team that is closer to being "playoff caliber."
Taylor Hall is a first round draft pick; Larsson was chosen 4th overall. Hall had 328 points in 381 Oilers' games. Larssons's stats don't really stand out. The Oilers need stronger defense; that is why the Oilers picked up Larsson. Teams recruit according to need. Yet, a prime forward is always a more valuable asset than a defenseman. Hall is now one of the highest paid forwards. Forwards are versatile in that they play defensively as well. In all, the trade does seem to favor the Devils. The Devils made a smart move. Hall will make a significant contribution to the Oilers team.
First and foremost, this is NHL hockey, so it seems unlikely to matter to most of the general population. Second, while the trade is lopsided, there are almost always reasons unseen that make the trade of equal value. Some may recall in the late 1990's when the Cleveland Browns were reborn, the 49ers sent several players for 'consideration' in trade. That meant the 49ers needed to clear salary cap space to save the players they actually wanted on the roster.
