I know folks here are attached to Koufos but he has a player option for 2018-19, and, as good as a sport as he's been so far, I'd have to believe he declines that option and walks next summer. Now, if you can trade him for something like a late first, AND replace him with someone like Aldrich, while netting another late 1st, why not? Are his contributions/mentoring to Papa worth two first rounders?
I am a Koufos fan but yeah, I'd be fine with moving him depending on the return. He's a very solid player on a cap friendly deal and the Kings are still rebuilding.
If they chose to trade him and use their caproom to absorb contracts and came away with 3-4 1st rounders over the next two years I'd be fine with it. It means more minutes for the young bigs and more assets going forward that can either be used to draft more young guys or included in trades to reshape the team.
The West is going to be nasty for a few years. It's not a bad time to develop young talent and rebuild smartly.
