Never a flashy player, Collison did the little things and seemed to be the consummate glue guy in the locker room through thick and thin in Oklahoma City. Collison befriended Kevin Durant, Russell Westbrook, and James Harden during his time in OKC, and nary a bad word was said about Collison during his tenure with the Thunder.

During the jersey retirement ceremony, Collison got quite emotional as he saw his #4 in the rafters:

While Collison’s numbers might not immediately jump off the page as jersey retirement-worthy, he spent 14 years with the Thunder organization, even starting out the first four years of his career when the team was still called the Seattle Supersonics.

Collison, aka Mr. Thunder, outlasted Durant and Harden in OKC, and he was a pro’s pro through it all.
