Cam Newton threw an INT in practice and he thought the guy showed him up so they got into a fist fight.... Not sure I want my 100 million dollar QB fighting anyone let alone his teammates.
Especially in practice. To me, that sounds like Cam got frustrated and focused it on the wrong guy.
Fun fact, in little over a week of training camps, Aaron Rodgers has thrown 5 interceptions. The same amount that he threw in the 2014-15 regular season.
