a net gain average of 38.7. However, the Dolphins' defense was a little suspect. They tied the Houston Oilers and the Minnesota Vikings for the most rushing yards allowed during the regular season (4.7 yards per attempt), and ranked just 19th in fewest yards allowed (5,759). The main bright spots on the defense were safeties, brothers Lyle and Glenn Blackwood, along with Pro Bowl inside linebacker A. J. Duhe, Pro Bowl nose tackle Bob Baumhower, and defensive end Doug Betters. Glenn Blackwood had picked off 6 passes during the season and returned them for 169 yards, while Betters recorded 14 sacks and a fumble recovery. Linebacker Charles Bowser was also a big contributor, recording 9 sacks and one fumble recovery. Despite their defensive flaws, the Dolphins' powerful offense led the NFL in scoring (513 points) and total yards gained (7,064), and helped the team reach an AFC best 14–2 regular season record. San Francisco 49ers The 49ers advanced to their second Super Bowl in team history after becoming the first team to win 15 regular season games since the league expanded to a 16-game schedule in 1978. Much of the hype surrounding the team was their offense, which boasted five Pro Bowlers. Quarterback Joe Montana recorded 279 completions out of 432 attempts for 3,630 yards, 28 touchdowns, and only 10 interceptions. Fullback Roger Craig was one of the 49ers' major weapons, both rushing and receiving. Craig was the team's second-leading rusher with 649 rushing yards and 7 touchdowns, and also caught 71 passes for 675 yards. Pro Bowl halfback Wendell Tyler, who had rushed for a team record 1,262 yards during the regular season, recorded 7 rushing touchdowns, and also caught 28 passes for 230 yards and 2 touchdown receptions. Tight End (and former fullback) Earl Cooper also made an impact with 41 receptions for 459 yards and 4 touchdowns. Wide receivers Freddie Solomon and Dwight Clark also were deep threats, gaining a combined total of 1,617 yards and 16 touchdowns. Up front, three of the 49ers' five starting offensive linemen, Randy Cross, Fred Quillan, and Keith Fahnhorst, had been selected to play in the Pro Bowl. Overall, San Francisco's offense finished the season ranked second in the NFL in scoring (475 points) and fourth in total yards (6,544). Although they did not get as much media attention as the offense, the 49ers' defense led the league in fewest points
