His physical talent warrants the 1 and 3, but the risk he would bring to a new team and the situation he has put the Broncos in will reduce that cost significantly. No on should pay near that for him.
Also, getting so many high draft picks is too expensive for a team - they would end up trading some of them down by draft day, and my not get 100% value since others will know they cant't afford all those high picks.
Also, as a Jets' fan I would not give up Harris (a good citizen and hard worker) for this malcontent. That would send a bad message in year one of a new regime. Hell, I'd chase after Matt Jones and deal with the inner demons he is fighting, rather than the attitude and lack of regard for his teammates that Marshall continues to display.
