"The greatest all-around athlete I've ever seen or hope to see." -MSU Coach Biggie Munn
Carey was competitive in three sports becoming an All American in two, track & field and football.
Carey was also a three-year starter for the Michigan State basketball team playing for Naismith Memorial Basketball Hall of Fame coach Pete Newell.
Spartan football coach and College Football Hall of Fame member Biggie Munn called Carey "the greatest all-around athlete I've ever seen or hope to see." As a senior at State, he won the Chester L. Brewer Award, given annually to a graduating senior for "distinguished performance in athletics and scholarship, and for possessing a high degree of character, personality, competitive spirit and other leadership qualities which forecast a successful future."
1952 College All Star Team Selection
Carey was selected as a member of the Chicago Tribune's 1952 College All Star Team. Teammates on the All-Star roster included future NFL Hall of Famers Ollie Matson, Frank Gifford, Hugh McElhenny and Les Richter. Played at Soldier Field in front of 88,316 fans, the college stars lost 10–7 forcing the defending NFL champion Los Angeles Rams to come from behind to win. Carey caught a key pass in the All Star's 69-yard first half touchdown drive which temporarily put them in the lead.
1952 NFL season
Carey joined the Rams following the Chicago All Star game. In his first pro campaign he earned five regular season starts. This was despite a Ram roster which included future NFL Hall of Famers Elroy “Crazylegs” Hirsch and Tom Fears. Carey finished the season as the #2 receiver with 36 catches for 539 yards and one TD, a 61-yard catch vs. the Bears at Wrigley Field. He missed his one field goal attempt. The 1952 National Football League season resulted in a tie for the National Conference championship between Detroit and the Rams, requiring a one-game playoff. The Lions prevailed 31–21 in Detroit. Carey caught 3 passes for 30 yards, the longest went for 19. He fumbled once. The next week Detroit went on to defeat the Cleveland Browns in the NFL title game, while Carey married his college sweetheart Lynn Laue. Carey was named Rookie of the Year following the season.
1953 US Army Service
Carey and twin brother Bill were ROTC graduates of Michigan State. In ’53 both were called to service. Bob sat out the fall pro campaign and was stationed at Ft. Benning, Georgia. Following completion of his military obligation he returned to the Rams for the 1954 season.
1954 NFL season
The Rams squared off against Baltimore away in Memorial Stadium in the season opener. Los Angeles crushed the Colts 48–0 with Carey kicking a 21-yard field goal in the 1st Qtr. He finished the contest with 5 catches for 49 yards. In week two the Rams faced the 49ers in the LA Coliseum. The crowd of 93,621 saw the game end in a 24–24 tie. Early in the contest Carey suffered a serious knee injury. Reconstructive surgery followed, ending Carey’s second NFL season.
Arizona State University assistant football coach
Following Carey's severe knee injury, he spent 1955 in rehabilitation and was hired as end coach on the staff of eventual College Football Hall of Fame coach Dan Devine at Arizona State. The Sun Devils finished 8–2–1 for the season. Devine went on to serve in head coaching positions at the University of Missouri, the Green Bay Packers and at the University of Notre Dame, where he won a national championship in 1977. Following the '55 Arizona State campaign, Carey rejoined the Rams in LA for the 1956 season.
1956 NFL season and first retirement
Carey rejoined the Rams in August 1956. The receiving corps included “Crazylegs” Hirsch, Tom Fears, Bob Boyd, Leon Clarke and Carey. In another injury plagued season, Carey was limited to seven games, starting four. He finished the campaign with 5 catches for 60 yards and one touchdown, that on a 15 yard pass from Ram QB Bill Wade in the final contest played vs. the Bears in Wrigley Field. Following the season Carey announced his retirement.
Return to the NFL and 1958 season
In early 1958 the Chicago Bears acquired rights to Carey who had begun a second career outside of football. Following negotiations with his employer, Bears owner George Halas persuaded him to return to football. Carey, who was living in Chicago, joined the Bears at training camp in Rensselaer Indiana at St. Joseph's College. In ’58 Carey played in 11 games and had one reception made in the Bears 35–41 loss in front of 100,470 fans in the LA Coliseum. That catch proved to be the final of his career. The Bears finished the season 8–4, one game behind eventual World Champions the Baltimore Colts. He finally retired from football at season end electing not to return in 1959.
Charlevoix MI High School Athletics
Bob and his fraternal twin brother Bill grew up in an athletic family in northern Michigan. The six Carey brothers were well known in the region. Twins Bob and Bill were members of the legendary 1945 Charlevoix, Michigan football team that went undefeated and unscored upon. Bob stood 6 feet, 5 inches and weighed 215 pounds, while Bill measured in at 6 feet, 1 inch and 190 pounds. Bill himself earned five varsity letters at MSU and was eventually drafted by the San Francisco 49ers in 1952.
The 1945 team was coached by Ray Kipke, for whom Charlevoix's football stadium is now named, and the inspiration behind the change in spelling of the school's nickname from Raiders to Rayders. The 1958 Charlevoix squad repeated with an undefeated/unscored upon season coached by Bob's older brother Don Carey, a member of the Michigan High School Coaches Hall of Fame who, along with his brothers, had an outstanding athletic career at Charlevoix. No other high school team in Michigan playing full seasons has ever matched the twin accomplishments of Charlevoix's 1945 and 1958 teams.
The 1945 Rayders finished 6–0, with shutouts of Grayling, 25–0; Mancelona, 25–0; Boyne City, 33–0; East Jordan, 24–0; Harbor Springs, 64–0; and Pellston, 58–0. That team also went 8–0, won the conference championship, and finished the season ranked No. 1 in the UPI Class C poll. That team was dominant in its own right, outscoring its opponents 260–19.
The 1945 unbeaten/unscored upon team came during a truly golden era of football at Charlevoix that included the 1958 team. In the 15 years from 1945 to 1959, Charlevoix won 11 Northern Michigan Class C Conference championships, six of which were consecutive, and the teams combined for a sensational 92–11–4 record.
The 1945 team was composed of Dick Joliffe, Jerry Ypma, Frank Martin, Bill Carey, Bud Fox, Jim Roberts, Bill Joliffe, Don Zietler, Bernie Zietler, Bill Poole, Irving Manville, Nelson Sweitzer, Bob Crain, Dick Hardy, Jack Mol, Bernie Ward Jr., Don Brown, Em Howe, Lyle King, Bob Carey, Vince Olach, Jack Roberts, Cliff Lagerman, Bob Shanahan, Warren Shadko, Dick Donaldson, Arnie Loper, Des Milligan, Jack Kline and Pat Martin. The manager was Chuck Fairbanks, who went on to play football at Michigan State. Fairbanks later served as Head Coach at the University of Oklahoma, the University of Colorado (Boulder) and in the NFL as Head Coach of the New England Patriots.
