Fuzzy Thurston may never have made a Pro Bowl, but we have no problem ranking him high on this list. 

Thurston was not just the beneficiary of playing for a great dynasty in the Green Bay Packers during the late 50s and 60s; he was also a vital cog in their machine and part of their legendary "Packers Sweep" along with Hall of Famer Jerry Kramer.  Joining the Packers after spending a year in Baltimore, Thurston became a fixture on the left side of the O-Line and would become one of only four players to win six Championships (1958, 1961, 1962, 1965, 1966 & 1967).  Thurston is a member of the Green Bay Packers Hall of Fame, and while, as mentioned, he was never a Pro Bowler, he was a First Team All-Pro in 1961.

Ralph Neely was drafted by the Houston Oilers of the American Football League and the Baltimore Colts of the NFL, and he secretly agreed to play for the Oilers (it was kept secret so he could play for the University of Oklahoma in the Gator Bowl). 

Neely was ready to be an Oiler, but the Colts traded his rights to the Dallas Cowboys, a team he would rather play for, and "Big D" would land the Offensive Tackle.

The AFL was clearly the place for Neely, as he would play there from 1965 to 1977, which was his entire professional NFL career.  He was at his best in the late '60s, when he was a First Team All-Pro three years in a row (1966-68) and earned All-Decade Team honors.  The tackle helped them win two Super Bowls (VI & XII).  His career seemed to be tailor-made for Dallas.

There was a time when a case could be made that Wilber Marshall was the best Linebacker in football.  In 1985, he was a member of the most dominant team of the decade, the Super Bowl XX Champion Chicago Bears.  The year after, he was a First Team All-Pro, led the league in Approximate Value (23), and was a Pro Bowler for the first time.  Marshall was overshadowed by some of his teammates (William Perry & Richard Dent), but those in the know saw Marshall as one of the most versatile outside linebackers in the NFL.

Marshall would later join the Washington Redskins, and he was a significant cog in their dominant defense.  Winning Super Bowl XXVI, Marshall was a First Team All-Pro the season after and was the NFC Defensive Player of the Year.  He finished his career with a season in Houston, Arizona, and the New York Jets. 

The winner of the 1957 Heisman Trophy at Texas A&M, John David Crow, would be drafted 2^nd overall by the Chicago Cardinals and would blossom into one of the most versatile offensive players of his era.  Used at Halfback, Fullback, and Tight End over his pro career, he played half of his career with the Chicago (later St. Louis) Cardinals and the San Francisco 49ers, but he was never blessed with a loaded group around him, as most of his teams were not particularly good.  Crow was, however, very good, and he adapted effortlessly to his team's offensive needs.  A four-time Pro Bowl Selection, Crow scored 74 Touchdowns, splitting them between rushing and 35 from the air.  He would have 8,662 Yards from Scrimmage over his career, which is a great number for the 1960s, a decade in which he was named to the 1950’s All-Decade Team.
