QUARTERBACKS: It begins with Dan Marino, arguably the best in the game. For Marino, season 13 could be the lucky one. He's in line to break three of the major all-time passing marks (passing yards, touchdowns and completions). Still, until Marino wins a Super Bowl, many won't put him in Joe Montana company. If Marino goes down (as he did in '93), the Dolphins have Bernie Kosar in the bullpen.
RUNNING BACKS: The Dolphins hope to have Terry Kirby and Keith Byars for the entire season. Knee injuries claimed both during '94, and neither was available for the playoffs. Bernie Parmalee started 10 games at running back and finished with 868 yards. The Dolphins have ex-Buc Robert Wilson as a backup at fullback if Byars can't go.
WIDE RECEIVERS: This was the most intense aspect of training camp. The Dolphins added speedster Randal Hill along with former Redskins Gary Clark and Ricky Sanders. They'll combine with Irving Fryar and O.J. McDuffie to provide Miami with perhaps the top passing attack in the league.
OFFENSIVE LINE: Everyone knows about the left side. Tackle Richmond Webb and Keith Sims have been starters ever since being taken 1-2 in the 1990 draft. Questions lurk elsewhere. Second-year man Tim Ruddy has been handed the job at center, replacing Jeff Dellenbach. Chris Gray takes over at right guard with just two career starts. Veteran Ron Heller is at right tackle. The Dolphins invested picks 1-2 on tackle Billy Milner and guard Andrew Greene.
DEFENSIVE LINE: This could be the strength of the defense, and that's something Dolphins fans haven't been able to say lately. New additions Trace Armstrong (end) and Steve Emtman (tackle) give the Dolphins reason for optimism. Tackle Tim Bowens earned NFL Defensive Rookie of the Year last season. Armstrong will add depth behind starters Jeff Cross and Marco Coleman. Chuck Klingbeil has started the past three seasons at nose tackle.
LINEBACKER: If Marino is the leader of the offense, then Bryan Cox ignites the defense. Of course, Cox often infuriates opponents, but at least he has helped toughen a defense that was too soft for too long. Lining up outside Cox is Chris Singleton and Aubrey Beavers, the team's No.
2 pick in '94. Dwight Hollier is versatile and can play all three positions.
DEFENSIVE BACKS: Cornerback Troy Vincent proved last year he is fully recovered from his devastating knee injury in '93. Vincent had five interceptions. J.B.Brown is the other starter at corner, and Michael Stewart and Gene Atkins are the safeties. For depth, the Dolphins brought in former first-round picks Terrell Buckley and Louis Oliver. Oliver returns to the Dolphins, where he spent his first five seasons before going to Cincinnati last year.
SPECIAL TEAMS: Kicker Pete Stoyanovich is among the league's best, both in terms of accuracy and long-range ability. However, he must prove there are no lingering effects of his missing a 48-yard field goal in the closing seconds of last year's 22-21 playoff loss at San Diego. John Kidd took over the punting chores at midseason last year. He wasn't as bad as Jim Arnold, but he's no Reggie Roby, either.
COACHING: Don Shula goes searching for that elusive Super Bowl championship, something he hasn't won since 1973. Yes, he has won more games than any other coach (328), but he gets razzed for not delivering a title. Shula welcomes back a former coaching assistant, Monte Clark, who'll work with the offensive line, just as he did from '70-75.
