21. John Hannah
There’s nothing new about contract holdouts. The only difference is how widely the media reports them. In 1977, Hannah was one of the Patriots’ most important offensive linesmen. After a distinguished career, he was voted into the Hall of Fame. But it wasn’t always sunshine and roses for the player and the franchise. That season, he sat out for three games because of a dispute.

Eventually, New England acknowledged his value and offered him a lucrative extension. Hannah settled down and nothing more was said about it. He repaid the contract in style as he spent eight more seasons with the team. He even helped them to a Super Bowl appearance. Hannah was one of the best players of his generation and the franchise knew it (via UPI).
