The Rams traded their first- and sixth-round picks in the 2018 draft to the New England Patriots for Cooks and a fourth-round pick earlier this year.

Cooks will replace Sammy Watkins Alec Ogletree Jersey , who left for Kansas City in free agency, and provide a deep threat for quarterback Jared Goff and the Rams, who had the NFL’s highest-scoring offense last season.

Cooks was entering the final season of his contract and is happy to be staying in Los Angeles for the next several years.

”I just knew this was a place that I want to be for a really long time,” he said. ”As far as the years and all of that, I just let them handle that, my agent handle that, and just knowing I wanted to be here for a really long time.

”They took care of that in the way they thought was best and we agreed with it. Other than that I’m just excited to get Game One in, let alone years George Blanda Jersey , so that’s what I’m focused on now.”

Before joining the Rams, Cooks played in 58 regular-season games with 46 starts, and had at least 1,000 yards receiving in each of the past three seasons.

The fifth-year pro has 280 receptions for 3,943 yards and 27 touchdowns, and averages 14.1 yards per reception. He had nine 100-plus yard receiving games in 2016 with the New Orleans Saints.

”Brandin Cooks has shown himself to be a class act on and off the field since the first day he joined our team,” Rams coach Sean McVay said in a statement. ”He’s a proven professional in this league, and signing him to a long-term contract was always our goal. We’re excited to keep Brandin in a Rams uniform through 2023.”

LOS ANGELES CHARGERS (9-7)

New faces: C Mike Pouncey Kyle Emanuel Jersey , TE Virgil Green, S Derwin James, LB Uchenna Nwosu, QB Geno Smith, PK Caleb Sturgis, PK Roberto Aguayo.

Key losses: S Tre Boston, TE Antonio Gates, DL Jeremiah Attaochu Jeremy Hill Jersey , TE Hunter Henry (injury), CB Jason Verrett (injury).

Strengths: Ample talent in place to build on last season’s finish of nine wins in 12 games. Philip Rivers back for 13th consecutive season as starter along with formidable receiver corps led by Pro Bowler Keenan Allen. Pouncey already giving boost to run game with Melvin Gordon. Defense largely unchanged, but restocked with draft picks including James, Nwosu. Edge rusher Melvin Ingram has been monster in preseason. Have one of NFL’s easier schedules and have five-game winning streak at tiny StubHub Center, clearly unaffected by presence of opponents’ fans.

Weaknesses: Already lost starting TE Henry, former Pro Bowl CB Verrett to season-ending injury. Defense could be uneven, possibly lacking depth with questionable quality at linebacker and interior line. Run defense still not impressive after struggling last season. Still waiting to identify new kicker after four guys took turns failing at position last year, likely costing playoff berth with early-season woes.

Fantasy Players To Watch: WR Mike Williams. Last season’s seventh overall pick made no impact after starting slowly due to injury. That could change in huge way this season. Tall Nick O'Leary Jersey , speedy receiver has been outstanding in practices and preseason games, presenting big target for Rivers. Williams could be huge bargain in many leagues.

Vegas Says: Super Bowl 15-1. Over/under wins 9.5.

Expectations: Bolts believe they’ve got Super Bowl contender after encouraging finish to last season. Season opener against Chiefs should establish early favorite in AFC West. Rivers poised for another strong season with no signs of slowing down. Continuity on roster and coaching staff should boost chances. Must survive six-week midseason stretch with only one home game and trip to London. If Chargers can avoid injury problems that popped up repeatedly for previous teams, future looks bright.
