The fluidity of hockey and subjectivity doesn't make this a worthwhile stat.
Say a defenseman pinches in on the powerplay. A forward doesn't drop back. The puck floats high up to the blueline, and the lone defender jumps to keep the puck in, but misses and falls. This leads to a shorthanded breakaway and goal. Whose error is it?
Is it an error if you enter the zone early and are offside? What if the team recovers?
What if a player passes while in a prime scoring position, and his teammate shanks the shot?
Without knowing what sort of errors are made, it's pretty useless. At least with baseball, there are few things that count as an error.
