With receiver Puka Nacua out for their game on Sunday against the Jacksonville Jaguars in London, the Rams are counting on Davante Adams, Tutu Atwell and Jordan Whittington.

Adams, a three-time All-Pro in his first season with the Rams, has been targeted 55 times. He has 26 catches for 396 yards and three touchdowns.

Adams and quarterback Matthew Stafford have connected on several dynamic plays, but their timing remains a work in progress.

“It's not how I drew it up as far as efficiency goes,” Adams said. “I think we both would've liked to be a little bit more efficient, but I know for myself over the last few [games], just based off how we started, [there’s been] a little bit of pressing.”

Stafford put the onus on himself.

“There's been some good ones,” he said. “There's been some missed ones. I would take the majority of the blame on a lot of those and just give him a better chance on a couple.”

Adams rose to stardom while playing eight seasons with Aaron Rodgers with the Green Bay Packers. But that connection also took time, Adams said.

“It definitely didn't start off the first couple years, let alone the first couple of games the way that we got going,” Adams said. “Not that we have another 10 years to go, but it takes time. It's not easy.

“Puka and Matthew have been playing together for years now and they have a little better understanding of where one another is going to be, what to expect, and just making it work. It's been a few where there’s really no excuse for me or him. We just have to put it together.”

Atwell will be back after sitting out last Sunday’s victory over the Baltimore Ravens because of a hamstring injury. Atwell has four catches on nine targets, including one for a long touchdown.

But he said he was not concerned about targets as much as affecting the game in other ways. The speedy threat opens opportunities for Nacua, Adams and others.

“Every opportunity we've given him, he’s seized it,” Stafford said. “I don't see anything different happening. If he gets more opportunities in this game, I have a ton of trust in him.”
