I really like this deal because there's a lot more winger options in FA than Center. Nelson has been solid for us, and looked to have improved under Trotz last year. Reasonable term and AAV for a 27 year old. Nice to have him locked up before other teams can start talking to him.
IMO, if Lee won't take a team friendly deal, we should roll the dice in see what we can do in free agency/trade. We have to look for players that will fit in here over the next 5 years, not reward players for what they've done the previous 3 years.
