Gut instinct: Derian Hatcher feels like he's got the team to beat this year, but wants to beef up his top 6 and add a top-pairing defensemen to shore up the deal. We send Raddysh and Sambrook for Jamieson Rees, 3 or more 2nds, a handful of other lower rounds picks, and possibly Colton Kammerer, who, if included, would decrease the number of picks.
Sarnia, IMO, makes the most sense with arguably the best 01 who'd be on the table. Gotta think that Sarnia, Soo, Hamilton, Kingston, and Kitchener are best bets to go all in. And given the enormity of a trade like this, it's hard for a rebuilding GM to stomach the trade not centering around a 16 year old first rounder. Rees is far and away the best one out of the teams mentioned above: Hayden Fowler has been buried on the Soo's depth chart and hasn't put up the numbers to warrant that much attention; Connor McMichael isn't doing anything special in Hamilton (although Arthur Kaliyev is, and he would have been a first rounder had there not been reporting concerns, but he's probably untouchable); Cody Morgan has been decent in Kingston, but doesn't have Rees' ceiling; and Grayson Ladd has been a bust thus far in Kitchener.
That leaves Rees. Hope that's what happens - kid is a stud. Don't know if Sarnia has the draft cupboard to make a move of this magnitude, but if they do, it's the best fit from where I'm sitting.
