Backup SF is a need. It might be one we can work around but in an ideal world you want a 6'8" - 6'10" that Lebron/Rashard Lewis/Lamar Odom can't easily shoot over..or post up too easily.
That guy for us right now is Brian Scalabrine. I think Danny can do better. I would personally give up some BBIQ for a guy with a better body like Balkman or a go for a total upgrade in all aspects with a guy like Battier (I think he might be injured though). Or even get just another "quick" PF like Warrick to fill in a bit.
How do you upgrade a 24-2 team? You determine which players in your rotation are your worst players and you replace them or knock them down in your rotation. It's straight forward for the C's. Our backup center (BBD) and our backup SF (Scalabrine) are the worst guys.
The fact that TA can fake it against some SF doesn't really change the path Danny should take..
