Tom Sestak, defensive tackle
Tom Sestak was the Aaron Donald of the AFL, dominating offensive lines from the moment he entered the league in 1962 until his retirement after the 1968 season. He was selected by the Bills with 132nd overall pick, but was also selected by the Detroit Lions of the NFL with the 220th pick. He chose to play in the AFL with the Bills and became a key part of the Bills AFL championships in 1964 and 1965. The one thing likely keeping him out of the NFL Hall of Fame is he played a relatively short career that spanned only seven seasons.
During those seven seasons, he tortured opposing offenses. He came in third in Rookie of the Year voting, was voted to four Pro Bowls (back when Pro Bowls meant something), and four All-Pro teams, including three first-teams. In 1965, he came in fifth in the AFL Player of the Year voting. During those days, sacks were not an official stat; however, according to Pro-footballreference.com, he recorded an unofficial career sack total of 52, including 15.5 in 1964. He is a Bills Wall of Fame member and was voted to the Silver Anniversary Team in 1984.
