Steph is joined by Chris to discuss the state of the 49ers defensive line from top to bottom: Will Bosa see a new-contract slump? Will Javon Kinlaw in a "6th man off the bench" type of role be better for him? Might Arik Armstead's role change with Javon Hargrave clogging up the interior? Does Drake Jackson make the second-year leap everyone is expecting him to? Who is the next reclamation project success story?
