All Pro linebacker Von Miller returns to the Broncos' lineup Sunday following a six-game suspension for violating the league's substance abuse policy. Many have told me he is in the best shape of his life and seemingly has a renewed focus on making smarter decisions. Miller who will be suspended for an entire season if he fails to abide by every detail of the NFL's drug-testing policy reported for practice at 270 pounds last week -- he entered the NFL around 240 pounds -- still displaying the kind of blinding speed that hastened his development but now with an upper body to match the power in his legs and trunk. Miller has paid much better attention to his diet and notoriously late and absent-minded at times has been more prompt and focused sources said. In addition to working out at the Broncos' facility during his suspension he spent time working with Chuck Smith an esteemed pass-rushing coach. He has also spent more time watching film and taking a more nuanced approach to the game team sources said.
