Cream Of The Crap

AITOOW is aware that baseball teams get a supplemental first round draft pick for every free agent they don't resign at the end of the year? So smart GM's have started to load up on scrubs (that they have no intention of resigning) at the end of every season. Doesn't this work against the leagues purported aim of trying to create parity (giving the worst teams the next generation of best players)? The teams with the most money or who are in the playoff chase, are usually the ones trading for these players at the trade deadline. Is this all about trying to goad the mid-level teams to compete against the Sox and Yankees?
