A look at Oakland Raiders players who were “up” and those who were “down” during the 2015 season:

UP

QB Derek Carr : Carr took another step in his development. His 32 TD passes came within two of tying Daryle Lamonica’s franchise record of 34 set in 1969. His 698 completions are the most by a passer through two his first two NFL seasons, and he joined Rich Gannon (2001 and 2002) as the only passers in Raiders history to complete 350 passes in a season. His 53 touchdowns to 25 interceptions in two seasons is a pretty good differential for a second-year quarterback.

OLB Khalil Mack : Mack, the Raiders’ first-round pick in 2014, recorded a season-best 10 tackles in the season finale at Kansas City and finished with 15 sacks, one shy of the franchise record set by Derrick Burgess in 2005. The highlight came with a five-sack performance against Denver, including forcing a fumble that led to a safety.

WR Amari Cooper : Cooper, the Raiders first-round pick in 2015, caught 72 passes, the most in NFL history by a wide receiver 21 years or younger. Cooper, who turns 22 next June, also recorded 1,070 receiving yards, the most by a wideout 21 years or younger. Cooper’s six TD catches set a franchise record for TD receptions by a rookie wideout. Cooper played the last two games a foot injury, limiting him to four catches for 30 yards.

DOWN

CB DJ Hayden: Hayden was a reach when taken with the 12th overall pick in the 2013 draft, which wasn’t his fault. Though he finally was able to stay healthy and play a full season in 2015, he had just one interception, giving him three career picks -- one per season.

LB Curtis Lofton: Lofton joined the Raiders as a big-money free agent, but he hasn’t been the tackling machine Oakland envisioned when handing him a three-year, $18 million contract. Though tackles can be a questionable statistic, Lofton recorded at least 100 tackles in each of his first seven NFL seasons with Atlanta and New Orleans -- averaging 143 per season. He collected a more modest 77 stops in 2015 with just one sack, one forced fumble and no interceptions.

FB Marcel Reece: Reece earned Pro Bowl honors for the fourth straight year only to see it go to waste with his four-game suspension last week for violating the NFL’s policy on performing enhancing substances. He’ll miss the first three weeks of the 2016 season as well as the Pro Bowl,
