GREEN BAY, Wis. — Packers safety M.D. Jennings stood in front of his locker and patiently answered every question about the final play in last year’s Seahawks game. Yes, that one, with the replacement referees and Golden Tate’s disputed touchdown.For as much as others bring up the infamous call, Jennings isn’t stuck in the past. He’ll have more pressing matters on his mind when Seattle visits Lambeau Field for a preseason game Friday night.The post-Charles Woodson era is under way in the Green Bay secondary, where Jennings is locked in a training camp duel with Jerron McMillan at strong safety.“It’s close, close enough that we haven’t made a decision yet,” safeties coach Darren Perry said.
