Now that Davon House is back with the Packers, coach Mike McCarthy expects him to regain the confidence he had during his first stint in Green Bay. The six year veteran started his career with the Pack before moving to Jacksonville for two seasons — but House struggled early last year and was let go after he intercepted four passes for the Jaguars in 2015. Despite House’s return, the Packers are still expected to use a committee to replace corner Sam Shields — who may have ended his career with a concussion in last fall’s season opener. At this week’s N-F-L owners’ meetings, Packers’ president Mark Murphy said he watched all 244 concussion plays from last year in his role on the league’s competition committee — and he said it was “depressing” to watch Shields’ injury because it came on a minor hit.
