Raymond Berry-20th Round
Didn't start in High School until his Senior Year, and his dad was coach. Only caught 33 passes at SMU. One leg shorter than the other. Was near-sighted and had to wear contacts during the game. Slower than molasses.
However, he worked so hard and attention to detail, he became the #40 all-time great player in NFL history. Unitas-to-Berry was the Montana-to-Rice combo of the day. Dropped only two passes his entire career. Retired with 631 receptions, and was inducted in the Hall of Fame in 1973.
His post-playing career was pretty good too-led the patriots to their first Super Bowl, and had winning teams in New England until his last season in 1989.
