Need help with this jersey, possible 1970's Packers

[Bertuzzi44]

Need help with this one. All sewn on, 3/4 sleeves, maker tags have been removed but there is an outline on the front bottom hem area, size 46 tag on the inside neck, Name on the back has been removed and it was a long name. Jersey is a Durene style and shows great use with numerous team repairs. I tried to photo match it to a John Brockington Green Bay Packers jersey but could not find a decent enough picture. Any help would be greatly appreciated and additional photos upon request...
