Jack Sikma is the Bert Blyleven, and not just because of the Nordic surname. Now that Artis Gilmore is in the Hall of Fame, there's a vocal contingent nominating Sikma for the title of Biggest HOF Snub, and with good reason. Across a 15-year career, was a rare breed: An annual double-double center who also once led the league in free throw percentage. As a rookie, Sikma was a key contributor to the Sonics team that lost the Finals in seven games to the Bullets; in his second year, he put up nearly 15 and 12 to help lead Seattle to its only chip. After joining the Bucks in the twilight of his career, he developed a three-point game, becoming one of the first big man arc assassins for a Milwaukee team that was a perennial on-the-cusp contender.
