This NFLN video describes the number five draft trade of all-time, the Dallas Cowboys trade with Seattle for the right to draft running back Tony Dorsett: http://www.nfl.com/videos/nfl-game-highlights/09000d5d80211b0f/Top-Ten-Draft-Trades-Tony-Dorsett The video concludes with the statement that the last pick Dallas traded to Seattle was ultimately dealt to San Francisco, and that the 'Niners used that pick to select Joe Montana, making Seattle look even worse for doing the deal. There's just one problem: its not true. I don't know where NFLN got their info, because those drafts were two years apart, and as far as I can tell, the '77 trade did not involve any of Dallas' '79 draft picks. Montana was actually taken by SF using a third round pick in the '79 draft obtained from Dallas (via Seattle) in the Bill Gregory (not Tony Dorsett) trade: on Aug. 28, 1978, the Seahawks traded their third round pick in the 1979 draft (#76 overall) and their 6th round pick (#155) to the Cowboys for DT Bill Gregory and Dallas' third round pick (#82). Later that day, the Seahawks traded S Bob Jury and the third-round pick (#82) they obtained from Dallas to the 'Niners in exchange for the 'Niners third-round 1979 draft choice (#57), with which they drafted LB Michael Jackson from Washington. The Cowboys used their third round pick (#76 from Seattle) on TE Doug Cosbie from Santa Clara. The Niners used their third round pick (#82 from Dallas via Seattle) on QB Joe Montana; see: http://seahawks.cypressconsulting.net/Team/AllTimeTrades.aspx?d=197 So it wasn't Dorsett for Montana; more like Bill Gregory for Doug Cosbie, and Jury / Jackson for Montana. Still, not bad deals anyway you slice it!
