Jones signed for 8 years because the org was still trying to win. They brought in Jones, MAF and Jake McCabe that off season. They already had Kane, DeBrincat, Strome, Toews, Kubalik, Dach and Hagel. The org sold to Jones that they still want to contend. So he signed. Two thirds into his FIRST season they pivoted on that promise when KD took over and began the rebuild when they traded Hagel. They would trade DeBrincat at the draft. They let Kubalik and Strome walk for nothing. The next year they traded Kane and let Toews walk also.
These last 3 seasons of Blackhawks hockey have been the worst I've ever seen. They easily beat any 3 year stretch from 98-06. It's not Jones' fault this team has been littered with AHLers/Fringe NHLers and replacement level players for the past 3 seasons. He didn't sign up for that. I don't blame him for wanting out.
