The only people I would keep are Stone, Erik (maybe, depends on contract ask), Chabot and the new guys obviously. I'd like to keep Duchene, but not at more than 5.0, not convinced on him.
For Erik I'd want the full buffet package. Say Tampa Bay wans him, Brayden Point, Sergachev, 1st in 2018, 1st in 2019, something along those lines.
For detritus like Burrows, anything.
For Borowiecki, I'd honestly take an end table and some free meals at the receiving team's decent eateries, just get him off the team so I don't have to hear from or see him again.
For Hoffman, I'd need a very high end prospect (Marner, Zadina, lower than Laine) and a pick.
Essentially, all I want is draft picks, futures, etc. If I can trade Phaneuf or Ryan, I'd ask The Euge if we can retain 3.0-4.0 on them, reminding him that we're getting young people that won't be paid much for a while.
Trade anyone that is older or unskilled for anything you can get, rebuild on the fly, sort of, and go from there.
