I don't think there is a fix. I just want Danny to cover the cracks as well as he can.
I would've loved to have seen him sign Chris Andersen and Kenyon Martin to give the team some interior defense off the bench.
Edit: Sorry, that might be a bit unclear, by that I mean to say that I don't think there is going to be a way for Danny to make the team a favourite for the title. They'll always be a second tier title contender due to the aged performances of Pierce + Garnett and the lack of star talent behind them and Rondo. So just cover up the cracks as well as Danny can and go forward with that.
