The Houston Texans' defense has not always been a joyful thing to behold, unless you like suckage. But that could be quickly changing, in no small part thanks to aggressive, smart, talented players like linebacker DeMeco Ryans. NFL Rookie of the Year in 2006, he made the Pro Bowl the following year and in 2008 he's been anointed as the leader of the Texans' D. He'll be the guy wearing the radio headset in the helmet that previously only QBs could wear. Ryans came from the University of Alabama with a sterling reputation (off the field, too; he graduated in just seven semesters). Everything he's done so far in Houston has shown the reputation was well-deserved.
