Like SLRS I had a litter of American Blue kits that were very curious and mouthy. They were handled a bunch which may have contributed as they were pretty laid back temperament wise. As they grew into teenagers they started putting teeth on or grabbing clothes. They never holed my jackets or shirts and never bit down, they were very gentle but persistent. I would head press them to submit and they would come right back up, then put their mouths on me again. None of them had good coats and we ate all of them, but my current litter from a different buck doesn't do that at all. My New Zealand lines don't do it at all.
