Other options

None of those things would interest me.
Reeves is negative value because he's on a multiyear deal.
I thought Timmins looked okay, if not great, when he was here, but the staff obviously felt differently. They shipped him out for an AHL grinder when they desperately needed dmen. Whether it was on-ice evaluation or something off-ice, they did not want him, period.
Robertson is worth more to the Leafs than anyone else. Spurts of talent, always injured, undersized. Coyotes have plenty of forward depth and prospects, they don't need to roll the dice on Robertson earning time and staying healthy. Keep him and roll the dice while he's cheap, or ship him to San Jose for a third or fourth.

I'd send Dumba retained for a third and Chadwick. It'd be a good deal for both clubs.
