From what I was told in the last few days, they're monitoring the market at 3 more positions based on where the roster stands now, but their plan is for the young guys to fill the roles. If they fail to capitalize into TC, they'd consider making a move.
S - they really like the improvements Kane has made and believe in Brade too
ILB - Roquan and Trenton have been joined at the hip and they're expecting him to take that job
OL - they want youth to step up but they're not going to pass up a good vet if one were to become available
