Rookie defensive back Josh Jones is getting rave reviews as the Green Bay Packers are about to finish their three day minicamp today (Thursday). Coach Mike McCarthy has praised the entire corps of safeties, saying they’ve been consistently close to the ball. But Jones — a second round draft pick from North Carolina State — has played more snaps than almost anyone at practice, as he fits into a combo safety and linebacker spot that Morgan Burnett started playing last season. Defensive coordinator Dom Capers says now is the time to challenge players to see what they can really do — and by the time the preseason begins in August, Capers says he should have a better idea of each player’s endurance and performance levels.
