Von Miller continues to mature, he said, tries to learn from past mistakes. However, he hasn’t lost his playful side. Entering his fourth year in the NFL, the Broncos linebacker believes levity is necessary during training camp.

The premier pass rusher changed the focus Friday from his surgically-repaired right knee to his feet. Or more specifically his fashion. Miller rocked Tupac Shakur socks. He customized them, featuring a picture of the late rapper.

“I have always had crazy socks. Different colors. Neon. It’s camp; it’s grueling. Whenever I can make it a little easier or lift the guys’ spirits, I try to do it,” Miller said.

Miller isn’t finished. He plans to sport a pair with Biggie Smalls, and possibly a few teammates.
