I honestly think the biggest problem is the physicality of this team. Seemed like physical defenses, particularly secondaries, gave our wideouts problems. I relate that back to the TE position underperforming in part as well as Kupp being a rookie and Watkins not being fully in synch.
But also on defense. Rams just gotta get tougher in the trenches on D, and have plenty other needs too at LB. Physicality steps up in the playoffs every year, that's gotta be addressed IMO.
