Holy cow! A 4th round pick for pulling a Madden move??? Damn.
I'm serious that's exactly what New Orleans did. They pulled a Madden move. That's one of the moves you pull in order to stock pile draft picks. If you have a lot of cap room, you sign a FA to a big money deal with as little signing bonus as you can get away with, then you trade him off to another team for a draft pick.
Man, lucky New Orleans. They've made a few savvy moves since Payton took over. Drew Brees. They took out some of the trash on defense (Sullivan, got a good return man for him). They got Reggie Bush signed quicker than we can even get Jason Allen signed. Now they sell off Bennett, a FA they just signed this off season, for a 4th round pick!
