Duane Putnam was a 6^th Round Pick by the Los Angeles Rams from the Pacific University in 1952, and by '54, he would establish himself as one of the premier Guards in the NFL. 

Clem Daniels was signed as an undrafted (by both the NFL and AFL) by the Dallas Texans, but playing behind Abner Haynes in 1960 meant that you weren't going to see much playing time if you were a Halfback.  Daniels was traded to the Oakland Raiders, where he worked his way into the starting rotation, and from 1962 to 1966, he would finish in the top three in All-Purpose Yards.  Daniels went on a four-year streak of AFL All-Star Selections in 1963, and that year The Sporting News would name Daniels their version of the MVP as he was the league leader in Rushing Yards, Yards From Scrimmage and Yards per Reception.  Later in his career, although he was beaten up, he would help Oakland win the 1967 AFL Championship.  

Undrafted out of Southern in 1966, Rich Jackson was given a chance by the Oakland Raiders, where he played only five games.  Al Davis would trade Jackson to the Denver Broncos, but immediately it was a transaction that the Raiders owner would regret.
