I think it could be for a conditional draft pick, which will raise in value depending on how far the team makes it into the playoffs / how many games Campoli plays / etc. That said, I don't know that Gauthier has made many of those deals previously, so his natural tendancies may trump it.
Overall, I'd say he's worth a 4th round pick to a team that believes his offensive abilities will help their powerplay and moving he puck up 5-on-5. They'll also need to have a defense partner or system in place that will make of for his defensive gaffes.
If there are enough teams looking for a defenseman as we close in on the deadline (and I read that there are) &&& Gauthier actually takes the time to shop him, he may be able to raise the return to a 3rd round pick - at max - in my opinion.
