Up next on PFW's offseason review series are the Colts and Ravens with the Indy Star's Stephen Holder (@HolderStephen) and Jeff Zrebiec (@jeffzrebiecsun), respectively. Holder explains why it's not yet time to panic over Andrew Luck's offseason inactivity following right shoulder surgery, and goes in depth on the myriad changes rookie Chris Ballard has made to Indy's defense. Zrebiec discusses newcomer Jeremy Maclin and his potential role in a Ravens passing game that needs more downfield strikes from Joe Flacco; plus, how Baltimore is replacing injured nickel corner Tavon Young, retired ILB Zachary Orr and now-49ers pass rusher Elvis Dumervil.
