Vikings' Kevin O'Connell says he was concerned Za'Darius Smith would be 'too hyped up'

When Za'Darius Smith was released by the Green Bay Packers, he was quick to sign with the rival Minnesota Vikings. After signing with the team to make sure he could play the Packers twice a year, it's safe to say his move was personal. 

But professionally the move is working in Smith's favor, as he has already scored a sack this season against his former quarterback. His enthusiasm to don the purple and gold has shown, but head coach Kevin O'Connell was concerned there would be too much excitement. 

After the win against the Packers, O'Connell said in a press conference his biggest concern for Smith if he would be ''too hyped up.''
