The NHLN Notebook is a semi-regular feature of interesting hockey content from the past few days that doesn't quite deserve its own article.
In today's notebook, we look at Arizona possibly being on the move (again), Gary Bettman getting called out by Dr. Bennet Omalu who is the doctor that discovered CTE, and Bryan Bickell getting set to return to the NHL. Also, Dion Phaneuf may be asked to waive his no move clause to help Ottawa prospect younger defencemen come expansion draft time, and Dallas mulls over whether or not to sell at the deadline.
