Los Angeles Rams

Los Angeles Rams rookie Blake Corum could end up having some stand-alone value in fantasy aside from being a handcuff for Kyren Williams. But in Week 1, fantasy managers would be wise to see how he is used before putting him in the fantasy lineups in his matchup at Detroit. The Lions had a good run defense last year and Corum will be operating behind a healthy Williams on the depth chart. The Michigan product has the potential to score a touchdown in a short-yardage situation but until his usage is more defined it is best to take a wait-and-see approach with Corum. He has a high upside and could end up being a valuable player to roster in the second half of the season, but there is too much unknown in Week 1.

Los Angeles Rams running back Kyren Williams is one of the best fantasy options at his position but faces a tough matchup against the Lions in Week 1. In what should be a high-scoring game, the Rams figure to exploit the passing game against Detroit which allowed 15.79 fantasy points to opposing running backs last season, the best mark in the NFL in that category. Put another way, the Lions were the stiffest test for fantasy running backs last season. That could continue into this season. Williams made some plays in the passing game last season so that could help him a bit in this matchup. The other wild card is the unknown usage of rookie Blake Corum, who theoretically could take away goal-line carries from Williams. Add it all up and this is not an ideal matchup for Williams. Fantasy managers will still likely want to start Williams without a better option in most cases. But expectations should be lowered in Week 1.

Los Angeles Rams wide receiver Puka Nacua (knee) is officially off the injury report and is set up nicely for success against the Detroit Lions in Week 1. Nacua will line up against the Lions' revamped secondary of rookie Terrion Arnold and veteran Carlton Davis III. He should see success with Matthew Stafford under center and pick up where he left off during a breakout rookie campaign last year. He had a knee issue in the preseason but is ready to go. The BYU product commanded 9.4 targets per game last season and racked up 105 catches for 1,486 yards and six touchdowns. With Cooper Kupp back fully healthy the red-zone usage might be a bit of a concern for Nacua as Stafford seems to look for Kupp a lot in those situations. But Nacua should work the middle of the field on the short and intermediary routes and is a high-upside PPR play, who could be in for a huge game if he can find the end zone.

Los Angeles Rams wide receiver Cooper Kupp is fully healthy to begin the season and has the potential to perform as a WR1 in a favorable matchup at the Lions in Week 1. Despite the emergence of last year's rookie breakout Puka Nacua, Kupp remains a favorite target of quarterback Matthew Stafford. His ability to move around the formation helps him get isolated in one-on-one coverage where he can use his shiftiness and route-running savvy to beat opposing defenders. The Lions drafted Terrion Arnold and signed Carlton Davis III in the offseason and each could see time defending Kupp in Week 1. In a potential shootout played in dome conditions, look for Kupp to score a touchdown and potentially get to 100+ receiving yards in the opening week of the season.

Los Angeles Rams quarterback Matthew Stafford could be in line to have a very productive week as he visits his old team in Detroit for an SNF matchup against the Lions. The game is expected to have one of the highest totals of the week and Stafford has his full array of weapons (aside from tight end Tyler Higbee) with Puka Nacua and Cooper Kupp both healthy. Throw Kyren Williams and capable backup tight end Colby Parkinson into the fray and Stafford should have plenty of options to throw to against a Lions defense that allowed 19.4 points per game to opposing quarterbacks in fantasy last season. Stafford averaged nearly 20 points per game in games in which Kupp played last season. He should be plenty motivated in his return from Detroit and should be treated as a borderline QB1 in Week 1. He can be started with confidence in the right roster situation.
