He signs his name with the tagline "Notre Dame killer," and for good reason. Although he didn't win the Heisman by some lapse of voters' judgment (they took Archie Griffin), Davis was as much apart of USC tailback lore as Garrett, Simpson, White and Allen -- maybe even more for those who just focused on what he did in games against the Irish.
He scored 11 times against Notre Dame in three games, including six in '72 and four in '74. His return of a second-half kickoff in the game at the Coliseum in '74 ignited the greatest comeback in school history, down 24-6 to a 52-24 win.
He had 17 100-yard rushing games in his career, leading the nation in '74 with a kickoff return average of 42.5 yards per touch. All that from someone who stood just 5-foot-9 and weighed 183 pounds.
On top of that, Davis played on Rod Dedeaux's baseball team and won a national title in '73 and '74.
The New York Jets took him in the second round of the '75 draft, but he went with the new World Football League team, the Southern California Sun, which played at Anaheim. He predicatably led the WFL in rushing with 1,200 yards on 239 carries and 16 touchdowns in 12 games. He also threw for a TD and ran one back on a kickoff. After a year in the Canadian Football League, a tryout with the Tampa Bay Bucs (and John McKay) in '76, he got a short stop with the Rams (where he wore No. 23) and, four years later, with the Express to see what he had left.
If only Notre Dame had been on their schedules.
On SI.com's list of the greatest college football players who wore a particular number, AD has No. 28 locked up.

First runner-up:
==Jackie Robinson, UCLA football ('39-'40)
Led the nation in punt return average in both 1939 (16.5 yards) and 1940 (21.0 yards). His career average of 18.8 yards ranks fourth in NCAA history. As a senior in 1940, he led UCLA in rushing (383 yards), passing (444 yards), total offense (827 yards), scoring (36 points) and punt returns (21.0 average). In his two-year career, he rushed for 954 yards (5.9 average) and passed for 449 yards.

Second runner-up:
==Mort Kaer, USC football ('24-'26)
The Trojans' first consensus All-American (a year before Morley Drury), Kaer made it to the College Football Hall of Fame in '75. He led the nation in scoring in 1925 with 216 points (all rushing TDs) and still is in the Top 25 in USC's all-time career rushing list. A USC Hall of Fame inductee in 1997, he was also on the '26 track team that won a national title and finished fifth in the pentathlon at the '24 Olympics in Paris.

Runner-ups:
==Bert Blyleven, Angels ('89-'90, '92)
The last three seasons of his non-Hall of Fame career were spent in Anaheim -- he missed '91 with rotator cuff surgery -- where he had a 17-5 record in '89 and 131 strikeouts. He'd end up with 287 wins and 3,710 Ks (fifth on the all-time list) with a 3.31 ERA in 22 seasons. The curveball specalist was born in the Netherland but grew up in Southern California admiring Sandy Koufax.
==Mike Marshall, Dodgers ('74-'76)
Won NL Cy Young Award in '74 with 106 appearances in relief
==Wes Parker, Dodgers ('64-'72)
The Rawlings All-Time Gold Glove winner at his position, first base

Other No. 28s:
==Pedro Guerrero, Dodgers ('80-'88)
==Todd Hollandsworth, Dodgers ('95-'00)
==Clarence Davis, USC football ('69-'70)
==Albie Pearson, Angels ('61-'64)
==Steve Duchesne, Kings ('86-'91, '98-'98)

Sports Illustrated's pick for the all-time No. 28: Marshall Faulk, over Darrell Green and Blyleven
