Gregg Rosenthal will project post-draft starting lineups for all 32 teams, because there's no better way to celebrate the arrival of spring.
» David Johnson is the forgotten man in Arizona, but he's a sneaky pick to lead the league in yards from scrimmage if Kingsbury can maximize his pass-catching ability.
» This does not look like the roster of a team that just finished 3-13. The defense has a promising starting lineup, although the depth at many positions is lacking. The group will rise and fall based on how well some key free agents (Darius Philon, Jordan Hicks, Robert Alford and Terrell Suggs) integrate into the starting lineup. Haason Reddick showed improvement in Year 2. He'll get snaps in the base package, but leave the field on passing downs.
» Kingsbury and general manager Steve Keim should actually want more position battles. Other than cornerback and some receiver spots, there doesn't appear to be a lot of competition on tap for camp because of the lack of quality bench options.
Biggest change from a year ago: The offensive overhaul with Kingsbury and Murray will make this one of the more fascinating groups in the league to watch in September.
LOS ANGELES RAMS
» Actions speak louder than words when it comes to Todd Gurley's workload. No matter what the status of his knee truly is, the drafting of multi-faceted third-round back Darrell Henderson -- on top of giving restricted free agent Malcolm Brownsolid backup money -- indicates that L.A. will use more of a committee approach. (Note: This is what most smart teams do anyhow.)
» The Rams haven't exactly solved their edge-rusher dilemma. Dante Fowler Jr. has to prove he wasn't a one-month wonder, and Clay Matthews is a part-time player. They could use a young player like Samson Ebukam to step up, but most of the team's pass rush will still have to come from the defensive line.
» Eric Weddle was a smart free-agent signing, and second-round rookie Taylor Rapp looks like his eventual successor. The Rams haven't developed much young talent across the defense in recent years, partly because they've been so focused on offense, and partly because they haven't had many draft picks. Sebastian Joseph-Day and John Franklin-Myers are two names to watch on the defensive line.
» Marcus Peters is in the final year of his contract. It's anyone's guess how he'll perform after a career with some big ups and downs.
Biggest change from a year ago: This is suddenly one of the most stable rosters in football, as changeover on the offensive line is the team's biggest question mark.
SAN FRANCISCO 49ERS
» The wide receiver roles are very much up for grabs. Dante Pettis, rookie second-rounder Deebo Samuel, Marquise Goodwin, Jordan Matthews, Trent Taylor, Jalen Hurd and Kendrick Bourne all figure to be battling for snaps in training camp. There's a good chance the top four will split snaps evenly, although Pettis has some breakout potential.
» That's an extremely impressive starting defensive line on paper, with former No. 3 overall pick Solomon Thomas getting significant snaps off the bench. (And the line should be impressive, considering the resources poured into it over the years, especially this offseason.)
Biggest change from a year ago: Huge spending on a lackluster defense has raised the stakes for Year 3 of the John Lynch/Kyle Shanahan partnership.
» Offensive coordinator Brian Schottenheimer doesn't need an excuse to run the ball more, and this roster composition could push him in that direction. More two-TE sets (including Nick Vannett) would not be a surprise, and the Seahawks would love to get last year's first-round running back (Rashaad Penny) more involved in the offense.
» The receiver depth chart is a mystery after Tyler Lockett, who has experienced his own durability issues in the past. In a perfect Seahawks world, rookies D.K. Metcalf and Gary Jennings would step right into big roles. Backups David Moore and Keenan Reynolds seem like candidates to get a ton of preseason hype from in-love 12s before fading into the background when real games start.
» This defensive line has the potential to be disruptive if Ezekiel Ansah and L.J. Collier play well. Both players come with significant risk, but Ansah, if healthy, looks like a perfect fit in Pete Carroll's defense replacing Frank Clark. Quinton Jefferson and Rasheem Green will also be in the mix at defensive end. Jarran Reed and Poona Ford showed signs of being a dominant DT duo late last season.
Biggest change from a year ago: The shock of Seattle's roster turnover has worn off. So when will the next wave of Seahawks stars arrive?
