I think he's trying to hide it, but the loss of Perk may irreversably change the identity of this team along with it's winning prospects.
He loves Pat Riley, and Riley needs him to bring his Big 3 together.
Plus Miami is a lot closer to Orlando.
I believe if Doc goes to Miami he would pull a trade for Perk if possible.
The Big 3 era in Boston would be over....unless Jeff Van Gundy came as a result.
