Along a dangerous Buffalo front seven, linebacker Lorenzo Alexander may pose the biggest threat. Even without Marcell Dareus up front to help clear lanes, Alexander is still capable of rushing through nearly any gap, and he had more than a little success in 2016. After a 12.5-sack season, Alexander was selected to the second Pro Bowl of his career at the age of 33. He'll look to continue that success in his second season in Buffalo, and it will be up to players like Ron Leary to stop him. Leary, a free-agent pickup from Dallas, has proved to be a great addition along the Broncos' offensive line. A dynamic run blocker, Leary will also be challenged to help deal with a dangerous Alexander, who will be looking to get to Trevor Siemian.
