The least we can say is that Arber Xhekaj's return is not as successful as he would have hoped. The young player is clearly very nervous and afraid of making mistakes, leading to a much less effective performance.
Xhekaj was sent to Laval for two reasons: to improve his defensive game and to be more disciplined. He worked hard on both aspects of his game with the Rocket, but he has returned to his old habits with the Canadiens.
In reality, even his defensive game leaves much to be desired. He has been the victim of several turnovers, which is hard to explain considering he played so well in Laval.
Word is already spreading, and his return to the Rocket might happen sooner than expected. Jordan Harris is currently sidelined, and Lane Hutson and Adam Engstrom will likely arrive in the coming weeks. If his game doesn't improve, the opportunity might go to another defenseman.
