Rams who must deliver and Cardinals to watch

Rams who must deliver in the season finale against the Arizona Cardinals on Sunday. Kickoff is 1:25 p.m. at the Coliseum.

Defensive tackle Aaron Donald. The third-year pro and three-time Pro Bowl selection has played well while amassing a team-best eight sacks. The Rams need him to lead the charge to put pressure on quarterback Carson Palmer.

Receiver Pharoh Cooper. With Kenny Britt sidelined or limited because of a shoulder injury, Cooper could get more opportunities. Cooper has done well on kick returns — he had a 51-yard return last week — but he needs to show why he should be considered a threat on offense.

Left tackle Greg Robinson. The No. 2 pick in the 2014 draft was benched last week for the second time this season. He might not have played this week if Rob Havenstein had not been injured, forcing Rodger Saffold to move from left to right tackle. But with another opportunity, Robinson needs to protect Jared Goff.

Cardinals to watch out for Sunday:

Cornerback Patrick Peterson. Rams rookie quarterback Jared Goff did not play in the Rams’ Week 4 victory over the Cardinals so this will be the first time the top pick from the last NFL draft goes up against one of the NFL’s best cornerbacks. Peterson, a five-time Pro Bowl selection, has three interceptions.

Linebacker Markus Golden. With a team-best 10½ sacks, he is another player Goff must be aware of at all times — as a pass rusher and in coverage. Fellow linebacker Chandler Jones has 9½ sacks for a defense that is ranked third in the NFL.

Receiver J.J. Nelson. Receiver Larry Fitzgerald, who has 102 catches, and running back David Johnson (77) are Carson Palmer’s top targets, but Nelson also is productive. He has 37 catches for 492 yards and has scored six touchdowns.
