Last year: If the defensive line wasn't the Rams' strongest unit a year ago, it was 1A to the linebackers. The Rams improved from 31st to 15th in run defense, giving up 117.5 yards per game, and they finished tied for first in sacks (52). As for an encore, all the key players return and are expected to enter training camp healthy.
Coach: Long-time NFL assistant Mike Waufle returns for his second year with the Rams, and again will be assisted by Clyde Simmons, a two-time first-team All-Pro during a 15-year playing career that ended in 2000. Waufle, a Super Bowl champion when as assistant with the Giants, enters his 16th season as a D-line coach.
1. What's new?
Well, sacks leader Chris Long was married and restructured his contract to give the Rams some needed cap space. Plus, backup end William Hayes scored a three-year contract to return to St. Louis. Other than that, not a whole lot has happened since we last saw the Rams' front four enjoy a strong 2012.
