Looking forward to the offseason, it'll be interesting. One new factor to consider too is that Holland won't be saddled with salary-for-salary player trades. He can afford to take on higher salary players due to the cap space. So the answer may not come via free agency, but by trade.
It's not. He was offered more than Detroit's $6-million when he hit free agency. (It might've been the Devils to try to keep him at around $6.5-million, but I haven't looked back to confirm.) Regardless, he absolutely took a lower offer to play here. It was a big point made in the press when he signed here.
A Hometown discount is debatable.
