Rayfield Wright came to Dallas as a seventh round pick in 1967, where in his first three seasons, he was used as an Offensive Tackle, Tight End, and occasional Defensive Tackle.  By 1970, he settled in at Right Tackle, and it was there where he became one of the best at that position of all-time.

In 1970, the National Football League’s teams all passed on drafting Cliff Harris, the Safety from Ouachita Baptist.  The Cowboys invited him to training camp, and he was so impressive that not only did he make the team, but he won the starting Free Safety role. 

Perhaps one of the biggest snubs of the Pro Football Hall of Fame is Chuck Howley, though the beginning of his pro career did not make anyone think of greatness.
