Approved forms: Bison, Bison Chandler, Tyson "The Bison" Chandler. Other forms are pending approval.
Disclaimer: Another nickname may be used if Clyde comes up with something better on a game telecast. This is how we got "Wil the Thrill," after all. Having said that, Bison will still be acceptable nomenclature.
Thank you for reading this public service announcement, and please remember to refer to Tyson Chandler as Bison in all comments and game threads forthwith.
