A collective of eight 49ers sportswriters looks at the team’s history, roster building, offensive and defensive schemes, and the many characters and stories that these season featured. Nick Bosa planting the flag in Cleveland and skidding on his belly across a soggy Washington field. Kwon Alexander’s dominating linebacker play, his torn pectoral muscle and “Legendary” recovery. Raheem Mostert’s rise from a punt returner discarded by 6 teams to a dominating running back who gained 220 yards in a single playoff game. Cornerback Richard Sherman’s return to his future Hall of Fame form, as he led a group of unknown defensive backs to form the the most dominant secondary in the NFL. Rookie Dre Greenlaw’s heroics in both games against Seattle, intercepting Russell Wilson in overtime, then stoning tight end Jacob Hollister at the goal line on 4th down to win first seed in the playoffs. Playoff dominance, leading 27-0 against Green Bay at halftime of the NFC Championship Game, and rushing the Minnesota with six sacks on Kirk Cousins, who had been sacked only 26 times in the previous 16 games.
