The business of professional hockey is a cruel one.

Connor McDavid found that out Wednesday, after he learned the Edmonton Oilers traded Taylor Hall to the New Jersey Devils for Adam Larsson.

"It's definitely a shock," McDavid said, according to the Edmonton Sun's Rob Tychkowski. "Change is exciting, but it's upsetting to see a teammate, a dear friend, and my roommate go."

McDavid and Hall didn't play much together in their only season in Edmonton, as Leon Draisatil centered the left winger for the most part. But clearly rooming together resulted in a bond.

Like Hall, McDavid was drafted first overall by the Oilers, and immediately became the face - and presumed savior - of the franchise.
