"In their new roles, Hextall will oversee the Penguins' day-to-day hockey operations, reporting to Burke as his primary advisor. Burke will report to David Morehouse, the team's president and CEO."
Burke is replacing Karmanos' old role of being the intermediary between the GM and Morehouse. Have no problems with that. He and Hextall will work together to come up with a game plan for what they want the team to be like, and then he'll let Hextall do the trades and transactions and he'll deal with Morehouse.
