Week 11 at New England Patriots
The Rams are in a great spot offensively when both Cooper Kupp and Puka Nacua are healthy. Add in the healthy offensive line, and they have the potential for big weeks. Unfortunately for Kupp, when both he and Nacua are healthy, it looks like Nacua is more of the 1A and Kupp is the 1B. Nacua had 14 targets last week to Kupp's 7, but I wouldn't count on him doubling him up every week.
The Patriots are 16th aFPA against receivers this season, so it isn't a terrible matchup for the Rams passing game. Kupp is more likely to avoid Christian Gonzalez in the slot, but he'll see some of him. Whoever avoids Gonzalez more between him and Nacua will likely have the bigger game. Either way, Kupp is a WR1 this week and a must-start.
