Alexander- an undrafted (knees) WR out of Missouri in 2010, had flashes of greatness with the Rams and then the Chargers in 2011-2012. He had chronic knee problems. Lewis has been having nonstop knee issues since arriving to Rams. What is his condition? Does he have a chance to recover fully or is his knee a chronic condition that will only allow him to play once in awhile? He is a great physical specimen for OLB. If his knee is chronic, it was a waste of a draft pick. What do we know about his knee?
