For one to successfully coach Major League players, one does not need to have been a successful Major League player -- or even to have reached the highest level at all.
Look no further than the managers of last season's final four teams. The Mets' Terry Collins and the Cubs' Joe Maddon never made it out of the Minors as players, the Blue Jays' John Gibbons played in 18 big league games, and the Royals' Ned Yost caught 214 games over six seasons, posting a .566 OPS.
At the same time, that doesn't mean good players can't also teach, even if for some it might be difficult to explain something that came naturally. Joe Torre, Davey Johnson and Mike Scioscia are a few who have found success as players and managers.
There will be plenty of talent spread throughout Major League coaching staffs in 2016. The Padres hired Mark McGwire as bench coach, and the A's tabbed Mark Kotsay for the same position. Other managers and coaches who excelled as players include Omar Vizquel and Wally Joyner (Tigers), Scioscia and Charles Nagy (Angels), Terry Pendleton and Kevin Seitzer (Braves), Edgar Martinez (Mariners) and Chili Davis (Red Sox).
And none of those teams made this list of the five coaching staffs with the most accomplished playing careers. Because the vast majority of staffs don't run particularly deep in this area, only the top five from each club were counted, in terms of wins above replacement (WAR) per Baseball-Reference.com.
1. Miami Marlins (255 WAR)
Barry Bonds (hitting) 162.4, Don Mattingly (manager) 42.2, Tim Wallach (bench) 38.3, Brian Schneider (catching) 6.7, Frank Menechino (assistant hitting) 5.4
Boy, did the Marlins shake up this list over the past few months. That will happen when you fill your hitting-coach position with a guy who ranks fourth all-time in WAR, behind Babe Ruth, Cy Young and Walter Johnson. Bonds accrued more value than any other entire coaching staff combined, and even if you stop counting after 2000 -- before his 73-homer season -- his 111.1 WAR still would crack this top five.
While Bonds was in another universe as a player, the Marlins also added Mattingly and Wallach from the Dodgers. The former was on a potential Hall of Fame track before injuries intervened, as Mattingly racked up six straight All-Star selections, five Gold Glove Awards and an American League MVP from 1984-89, when he hit .327/.372/.530 with averages of 27 homers and 114 RBIs. Though he never received Mattingly's acclaim, Wallach earned five All-Star selections for Montreal between 1984-90, winning three Gold Gloves and two Silver Sluggers at third base, and leading the NL in doubles twice.
2. Washington Nationals (127.1 WAR)
Davey Lopes (first base) 42.2, Dusty Baker (manager) 36.9, Chris Speier (bench) 30.6, Jacque Jones (assistant hitting) 11.5, Mike Maddux (pitching) 5.9
Like Miami, Washington revamped its staff this offseason, firing Matt Williams and hiring Baker, who as an outfielder produced six seasons of 20-plus homers and a career OPS+ of 116. Baker brought along former Dodgers teammate Lopes, who made up for lost time after playing his first full season at age 28. A four-time All-Star second baseman who ranks 26th all-time in stolen bases (557), Lopes averaged a 107 OPS+, 12 homers, 49 steals and 4.3 WAR over his first eight years. Speier was a three-time All-Star shortstop for the Giants by the age of 24 and lasted 19 years in the Majors, while Jones averaged 21 homers from 2000-06.
3. Arizona Diamondbacks (124.6 WAR)
Matt Williams (third base) 46.4, Mark Grace (assistant hitting) 46.1, Dave Magadan (hitting) 21.1, Mike Fetters (quality assurance) 7.7, Ariel Prieto (coach/interpreter) 3.3
Arizona has fielded some seriously talented staffs in recent years. Take 2013, when Williams, Alan Trammell, Don Baylor, Steve Sax and Nagy all worked behind manager Kirk Gibson. Now, Williams and his 378 homers are back on Chip Hale's staff after his stint in Washington ended. Grace batted .303 over his career, topping the .300 mark nine times, and owns baseball's ninth-best walk-to-strikeout ratio since 1950 (minimum 8,000 plate appearances). Magadan posted a .390 career on-base percentage, including .382 in more than 400 plate appearances as a pinch-hitter. Fetters took a rather unique approach to pitching, which Grace once imitated in grand fashion during a blowout mound appearance.
4. Minnesota Twins (117.4 WAR)
Paul Molitor (manager) 75.4, Tom Brunansky (hitting) 21.8, Eddie Guardado (bullpen) 13.3, Neil Allen (pitching) 6.7, Butch Davis (first base) 0.2
Molitor, who had a strong first season at his post, easily leads all managers in WAR. A first-ballot Hall of Famer in 2004, the seven-time All-Star ranks 10th all-time in hits (3,319) and 11th in doubles (605), topping a .300 average and 500 stolen bases. Brunansky came to the Twins in a 1982 trade and averaged 27 home runs for the club over the next six seasons, tying his career-high of 32 while helping Minnesota to the 1987 World Series championship. For good measure, he once hit a rare inside-the-park grand slam and clinched the 1990 AL East title for the Red Sox with a memorable catch. "Everyday Eddie" Guardado picked up 187 saves and ranks 22nd all-time with 908 games pitched, including an average of 71 for the Twins from 1996-2003.
5. Chicago White Sox (107.5 WAR)
Robin Ventura (manager) 55.9, Harold Baines (assistant hitting) 38.5, Bobby Thigpen (bullpen) 7.8, Daryl Boston (first base) 4.4, Joe McEwing (third base) 0.9
Among third basemen, Ventura ranks 16th all-time in WAR, homers (294) and RBIs (1,182). The 10th overall pick by the White Sox in the 1988 Draft, Ventura won five Gold Gloves and posted a 117 OPS+ in his 10 seasons in Chicago. His 18 grand slams are tied for fifth-most in history with Willie McCovey, and that total doesn't count his "grand slam single" to win Game 5 of the 1999 NLCS for the Mets. Baines launched 13 slams and 10 walk-off homers over a career that spanned 22 seasons and included six All-Star selections. He ranks second all-time in hits as a DH (1,690), third in RBIs (981) and fourth in homers (236). Thigpen's 57 saves for the White Sox in 1990 set a Major League record and remains the second-highest total in history, while "Super Joe" McEwing put together a 25-game hit streak as a Cardinals rookie in 1999.
