I mean it's a fair question is it not? Especially considering they wanted full value from what I remember.
The question itself is fair and I don't really get the criticism of Friedman when he clearly speculates on something (thus the "I wonder..." part of the comment). Now, I don't think that necessarily means that Friedman came up with that thought on his own - probably likely that one of many people he talks to (maybe involved with the league or a team, maybe not) might've brought it up, but not there's any inside information here. Friedman is usually very good at differentiating between more random thoughts versus something grounded in insider information.
Now, I highly, highly doubt that Briere himself knew more than any other GM. At best, maybe he got to hear Hart's version of the story and wasn't quite convinced by it - who knows. But it wouldn't have been unreasonable for a new GM to trade a player he didn't draft or even sign as part of an organizational rebuild.
I think most GM's had a decent sense of the guys that
may have been involved, though it seems "only" 5 players are being charged while we've heard that 8-10 players were in the room at some point that night, so I doubt GM's knew for sure exactly which players were going to face charges or that charges were most certainly going to come - given that was not the result following the original investigation.
Can't fault Briere for seeing if there was any interest in Hart or other GM's for steering clear.
