Long doubtful; Quinn questionable

The Rams have ruled CB Jalen Ramsey (knee) out for Sunday's game against the Cardinals. Fellow outside starting CB Troy Hill (thumb) is doubtful after missing last week following surgery on a fractured thumb. That will leave L.A. without both starting outside corners, which obviously helps the matchup for Kyler Murray and his WRs. Unfortunately for Murray, the rookie QB is dealing with his own hamstring injury that has him questionable. The Arizona passing game still looks risky for fantasy.

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.
