Just saw that it's Bernie Kosar's birthday which reminded me of how crazy the 80s NFL Drafts were. I didn't get into the NFL Draft until the early 90's, so these were fun to learn about retroactively.
1983: John Elway refuses to sign in Baltimore, Jim Kelly signs with the USFL instead
1984: Bunch of the top prospects sign big money deals with the USFL
1985: Kosar causes chaos at the top
1986: Bo Jackson goes #1 but doesn't sign with Tampa after they accidentally on purpose made him ineligible for his senior year of baseball
Kosar was originally expected to be in the 1985 NFL Draft. Buffalo had the #1 pick but were going to take Bruce Smith (and maybe they knew it was a matter of time before they got Jim Kelly). Houston had the #2 pick and started to auction it off to anybody who wanted Kosar. Cleveland badly wanted Kosar but Houston wasn't going to trade with a division rival. Eventually Houston worked out a deal with Minnesota and sent #2 for #3 and #30.
But Cleveland figured out a loophole. Buffalo would also have the #1 pick of the Supplemental Draft a few months later, so the Browns worked out a trade with Buffalo for that pick while likely sending some back channel communication to Kosar telling him not to submit his paperwork to enter the regular draft. The NFL allowed Minnesota to try to convince Kosar to enter but in the end Bernie wanted to play for the Browns.
On draft day Minnesota traded #2 to Atlanta for #4 and #60. Probably not the ideal return for their original #3 and #30, but they did draft HOFer Chris Doleman.
