Which says they're not unhappy with him.
They could get a nice return if they wanted to move him, Dubois was unhappy and got himself benched and that didn't hurt his trade value.
It's a fortunate dilemma for Briere. Brink and Foerster have played above expectations, Farabee has rebounded, Couts and Atkinson seem close to 100%. I think one reason for signing Hathaway and Poehling was the worry he couldn't ice 9 NHL caliber forwards and wanted veteran depth (instead of rushing 2nd tier prospects) - now he has (10) top 9 forwards.
Only 7 games, something will give in the near future, but Briere shouldn't make hasty decisions.
