The more likely scenario is that Tennenbaum, in a desperation move, offers the Broncos an exorbitant amount of draft stock for Marshall and get him, still go 8-8, Tenenbaum gets fired and the Jets walk into the 2010 draft with nothing but a 6th round pick and a box of Mike & Ikes.
according to Schefter, the Broncos won't give up Marshall until next offseason unless they get a player that can help them this season in return....which I don't see happening
now if someone offers up their whole draft like you say, then I think that would change
