nice link, Clark looks like the obvious choice

more-
Clark attended Penn State University, where he played for coach Joe Paterno's Penn State Nittany Lions football team from 1976 to 1979. As a junior in 1978, Clark became the first junior to win the Lombardi Award as the best college defensive lineman. He was recognized a consensus first-team All-American as a senior in 1979.
The Green Bay Packers chose Clark in the first round (fourth pick overall) of the 1980 NFL Draft, but refused to play for them. Clark then chose to play for the Toronto Argonauts of the CFL instead to avoid playing for Green Bay. After two years in Canada, he played for the NFL's New Orleans Saints for seven seasons from 1982 to 1988, and joined the Kansas City Chiefs for one final NFL season in 1989.
He later played a single season for the World League of American Football's Barcelona Dragons. Clark was drafted in the first round of the supplemental draft by the Barcelona Dragons in 1991. His experience and leadership were key to the Dragons successful first season. Clark started all ten games and was co-leader in sacks with seven that season.
----------------------
forgot about being a #4 overall that went to CFL instead. Looked it up... Seems like he didn't want to play nose in a 3-4 and then GB GM Bart Starr thought he could draft him and force him to play it. It was somewhat a changing of the guard era when players first started bucking up against the system for what was best for them.

Don't remember why the Packers still owned the right to him after two CFL years. Saints gave the #11 overall pick to GB (WR Tim Lewis) in 1983 for him. That was prolly the most famous QB draft in history. Hebert was here so they weren't going that way but HOFers Jim Kelly was #14 & Dan Marino #27 that year.

1989 bankruptcy filing actually has a lot of his contract details-
Pursuant to Paragraphs 5 and 6 of the 1988-89 contract, Clark's salary was $575,000 payable in 16 equal weekly installments of $35,937.50 each over the course of the 16-game regular season schedule.
