Agreed. I definitely think Ainge and company knows that the roster is flawed and would like to make changes, but the market for our guys might just not be very good. Even with Rudy, we might be able to get a young wing and another piece or two, but moving him likely causes us to take a step back, at least in the short term. All the reporting suggests that Ryan Smith is unwilling to take a step back, so they likely hang on to Rudy for at least one more season.
I don't think they will trade guys just to trade them, especially if it could cause the team to regress at all next season. I'm sure they would love to move Mike but they may not find a deal that improves the roster, same for JC and Royce.
I could see one of the top 6 guys being moved but I also wouldn't be shocked at all to see them all back next season. I think Bogey might be the most likely of the top 6 to be moved because he likely has really good value.
