The Chargers' disappointing season partially stems from the lack of production from their rookie class. Melvin Gordon failed to play up to the lofty expectations that accompanied his arrival as a top pick. He didn't post a single 100-yard game as a rookie and looked tentative running between the tackles early in the season. With Gordon failing to add sizzle as a dynamic RB1, the Chargers' offense was forced to lean on a pass-happy approach throughout the season. On defense, though, Denzel Perryman did make an immediate impact as a tackling machine between the hashes. He led the team in solo stops and emerged as a disruptive playmaker in the middle of the Chargers' defense. Kyle Emmanuel was a bit of a surprise as a situational pass rusher off the edge. The first-year player registered one sack, grabbed an interception and flashed intriguing skills as a disruptor from the corner. Craig Mager finally cracked the rotation at the end of the season after battling through a hamstring injury (six missed games). The rookie needed some time to acclimate to the pro game, but his versatility stood out when he was given more opportunities. Undrafted free-agent Josh Lambo provided a pretty solid season as the Bolts' kicker, making 26 of his 32 field-goal attempts (with all six misses coming from 40-plus yards out). Grade: C+
