In reality and the way the season is going now, I don't think Shero will trade for someone like Hoffman unless it's a real fleece job. Meaning, he'll give Dorian a low ball offer and if Ottawa can't do much better as the deadline approaches, maybe Ottawa pulls the trigger.
So without all Ottawa fans going crazy, it would be like a second that can become a first (but unlikely the condition would be met) and maybe Steve Santini. Again, I understand Ottawa fans would be unhappy with this kind of deal, but that's my guess as to what Shero actually probably offered, which is why there wasn't a deal earlier.
