Khreem Smith strikes terror in opposing quarterbacks, bursting through offensive lines like an Alien bursting through a sternum. The veteran lineman shares not only knowledge learned from an extensive career full of championships in the af2 (Memphis Xplorers, 2005), AFL (Chicago Rush, 2006) and CIFL (Chicago Slaughter, 2009) and time in the NFL, but he shares his own brand of humor with teammates.
