A beast at Temple University, Francis Joseph "Bucko" Kilroy may not have been drafted but his hometown Philadelphia Eagles knew there was something special there and he made the team; albeit in a combined effort as in 1943 the Eagles merged with the Pittsburgh Steelers due to the depletion of talent due to World War II. 

Coming out of the University of Alabama, Shaun Alexander backed up Ricky Watters in his rookie season (2000), and after Watters' retirement, he would become the lead back for the Seattle Seahawks.  Alexander would go on to a five-year run where he exceeded over 1,000 Rushing Yards, but most importantly, would become a touchdown factory.  In 2001, he led the NFL with 14 Rushing TDs and would never go below that in the next four seasons.

While Rosey Grier was better known for being one of the inaugural members of the Los Angeles Rams' "Fearsome Foursome," the defensive stalwart was a better player in the first two-thirds of his professional career when he was with the New York Giants.  Grier helped the New York win the 1956 NFL Championship, and the two Pro Bowls (1956 and 1960) he was named to was as a Giant.  He would also be selected as a First Team All-Pro in 1956 and was a two-time Second Team All-Pro.  

Selected in the 2^nd Round out of the University of Arkansas in 1938, Jim Benton would go onto be one of the first great receivers in the history of the Rams franchise.  Benton led the NFL in Yards per Reception as a rookie and was named to the Pro Bowl in his second season.  He took 1941 off and returned to the NFL in 1942, and due to a heart murmur, he was not permitted to enlist in the U.S. Military for World War II.  He was loaned to the Chicago Bears in 1943 as the Rams were unable to field a team due to a depletion of talent but returned in 1944 and 1945 and 1946 but together two excellent seasons where he was the NFL leader in Receiving Yards.
