Conklin has played great. Mason, for the most part, has played very well....although the last game or two have been a bit below his standard.
While I think you have to reward the results on the ice, the coaches also have a lot of information from practice to take into consideration.
Me? I'd continue to give Mason the next start, but maybe be quicker to rotate Conklin in there. Last game, I felt like Mason was trying to do too much. He's not the best puck-handler, but I think he's trying to help set up the offense and getting outside his comfort zone. If the team was scoring a bit more, I think we'd continue to see the same high level of play from Mason that he's shown all year.
