I was monkeying with shamsports calculator.
This is the copy/paste of the moves I made for the Lakers to get this roster:
Starters: Rondo-KCP-James-Leonard-Love
Bench: Anthony-Wade-McGee-Stephenson-Wagner-Vet Min-Vet Min-Vet Min-Vet Min
They'd still need a vet min guys (Booker? Mbouh a Moute? West? Beasley? Crawford? Napier? Lopez? Larkin?
I don't think that's a championship team, but I do think it can make some noise.
