There was a time when midseason mayhem was the Miami Heat's approach to February. No sooner did Pat Riley arrive in 1995, then he turned his roster upside down at his first NBA trading deadline with the team, on Feb. 22, 1996 maneuvering 11 players in four transactions, with Tim Hardaway acquired as the ultimate prize. The following season, Jamal Mashburn was added at the 1997 trading deadline. A lull followed before Bruce Bowen was added in midseason in 2000, with other complementary pieces similarly added at midseason in subsequent years, from Alonzo Mourning to Derek Anderson to Eddie Jones. And then, just before NBA trading deadlines in 2008 and 2009 came blockbusters, first Shaquille O'Neal traded to the Phoenix Suns for Shawn Marion and Marcus Banks, and then Marion and Banks rerouted the following year to the Toronto Raptors for Jermaine O'Neal and Jamario Moon. And since that 2009 trading deadline? Crickets. That likely won't change this season, with the 2013 NBA trading deadline at 3 p.m. Thursday, when the Heat will be preparing for their nationally televised road game against the Chicago Bulls. To a degree, those 2008 and 2009 blockbusters merely were a preamble to 2010 free agency, setting the stage for the signings of LeBron James, Chris Bosh and Dwyane Wade. Since then, free agency has produced the majority of answers, from Mike Miller to Shane Battier to Ray Allen and Rashard Lewis.
