Long doubtful; Quinn questionable

The Rams lost CB Marcus Peters and CB Aqib Talib to injuries in Sunday's win over the Chargers. We'll see about the status of each starter this week, but a quick turnaround to play the Vikings on Thursday night won't help them.

Update: Peters is expected to miss 2-4 weeks with a calf strain, according to Ian Rapoport. Talib is having surgery on a high left ankle sprain.

Rams LB Mark Barron (knee) is active for today's game against the Jaguars. He missed the 1st 2 days of practice but returned for a limited workout Friday. Barron didn't miss any snaps last week, though, and is fine to keep in IDP lineups. DB Lamarcus Joyner (hamstring) is inactive for the 3rd straight game, though, despite returning to limited practices every day this week.

The Rams will switch their base defensive front to a 3-4 under new DC Wade Phillips, according to the Los Angeles Daily News. That could mean significantly different roles for a number of front-seven players. The most affected in fantasy terms will likely be Robert Quinn, who figures to move from DE to OLB. If that designation changes for 2017 on most fantasy sites, then his IDP ceiling will come down considerably. Aaron Donald will move from his 3-technique DT spot, but he'll retain DL eligibility. Phillips told the Daily News that if Donald doesn't fit your system, then your system isn't working. We'll trust the seasoned veteran DC to put the stud lineman in position to make plays. LBs Alec Ogletree and Mark Barron will face a big change as well, which could include taking on a lot more blockers in the run game. This will be a key defense to look at as we head toward the summer, regardless of your fantasy football format.

The Rams have hired Sean McVay as their HC. The 30-year-old becomes the youngest HC in NFL history. He already has 8 seasons of experience in the league, though, including the past 3 as Washington's OC. The 2016 Redskins finished 3rd in total yards and 12th in points, led by the #2 ranked passing attack. McVay's 1st order of business in Los Angeles will be Jared Goff, who is coming off a disappointing rookie campaign.

The Rams have fired HC Jeff Fisher. He finishes his 5-year stint with the team with a 31-45-1 record. None of his teams won more than 7 games or sniffed the playoffs. Most damning is that the Rams never showed any signs of progress under Fisher's watch. We'll see who Los Angeles tabs as its interim HC, but this will remain an offense best avoided in fantasy lineups the rest of the way. The Rams travel to Seattle to face a pissed-off Seahawks squad on Thursday night.

Update: Special Teams Coordinator John Fassel has been promoted to interim HC. Fassel has only been a HC for DII New Mexico Highlands University.
