As we hit the NHLs All-Star break, the races for the most prestigious individual awards are wide open. Jakub Voracek is still hanging on to the Art Ross Trophy lead, Pekka Rinnes injury could open up what appeared to be a two-horse Vezina Trophy race, Calgarys unexpected success has thrust captain Mark Giordano into both Norris and Hart trophy contention, and Johnny Gaudreau into the Calder Trophy mix. Most importantly, the list of viable Hart contenders has yet to be pruned to even a dozen names.

Injuries do not actually have that much influence in the final standings. Even the teams with the most devastating injuries, such as the Columbus Blue Jackets this season or Detroit Red Wings in 2013-14, are affected to an extreme of about eight points at most.

Taylor Hall is a 23-year-old, possession-driving, offensive powerhouse and a game-changing talent whose playmaking and power play prowess down the left side are almost without peer. For the Edmonton Oilers to trade him would be sheer madness -- even for a team that admittedly should start embracing off-the-board ideas such as that.

Multiply their AHL scoring by that magic number and you can get a fairly accurate picture of how they will do in the NHL.
