This is the first in a series of contributor pieces I am experimenting with, collaborating with others on articles in an effort to add even more of the type and quality of content you’ve come to expect from Cleaning the Glass without reducing my own output.

Dylan is a former G League Scout with the Atlanta Hawks and Assistant Coach with the Fort Wayne Mad Ants. You can find more of his writing at The Basketball Dictionary, and can follow him on Twitter @DylanTMurphy.
