I can't believe we're even talking about this, but it would be insane to trade Taylor Hall.
Admittedly, Hall is having a bad season by his standards, just like everyone else on the team. Half a decade of losing probably hasn't helped in that regard. But let's get down to the nuts and bolts of why you don't trade a player like Hall.
Here are Hall's even strength points per hour since he entered the NHL. His league ranking in brackets is based on all NHL forwards who played at least 30 games.
2014-15: 2.02 (81st)
2013-14: 2.91 (4th)
2012-13: 3.15 (6th)
2011-12: 2.07 (77th)
2010-11: 1.78 (158th)
Something's off this season (maybe a few things), but over the last two years Hall is one of the most elite point-producing forwards in the league. Even at his worst, as a rookie fresh out of the draft on a last place team, he was producing like a very good second line player.
Now let's look at his possession numbers. Corsi needs context, so below I've shown Hall's rank anong Oilers forwards (20 games played) in relative Corsi since he entered the league.
This is a bit crude, but it certainly shows how it's Hall who is driving the play for the Oilers. He's most often their best forward in terms of possession, except for last year when he led the team in scoring with 80 points in 75 games.
That offensive total last year is 1.07 points per game. Guess how many times a player has scored at least 1.05 points per game (45 games played) since 2005-06?
127. That's under 13 players per season on average.
I heard Paul Almeida on Lowetide's show today make a hilarious but sadly probable comment. What if the Oilers trade Hall for a top-six forward with some grit and a top-four defenseman? With another couple of pieces that's a good return, right? Except that the Oilers are about to lose Petry (top-four defenseman) and have already traded Perron (forward, grit)!
I hope the Oilers aren't stupid enough to trade Hall, but they keep reaching new levels of stupidity, so who knows.
