The Globe reported that we're interested in Gafford. They mentioned that we wouldn't have to trade away as much as we would for Zubac, but we would have to make the salaries work. OK salary cap experts, let's see some hypothetical trades! 
Hauser plus two minimums makes it work. I would rather it be Boucher+Tillman but it would more likely be Boucher + Minott.
This would be tricky as DAL already has 15 contracts. This trade would be a net +2 for their roster. They would have to work that out. Same for BOS who is at 14. -2 would put them at 12, below the allowable. All this can be worked out, but adds some complexity to the trade.
It does, but because Gafford makes $4+ million more than Hauser, monetarily it is a near wash for them this year, and cuts $6 million from the payroll next year. It is, however, why I think the would need Minott over Tillman.
