http://games.espn.go.com/nba/tradeMachine?tradeId=6agvqz7 The Boston skinny:
Rondo, Garnett, Jermaine O'Neil, Avery Bradley + draft picks
FOR
Steve Nash, Dwight Howard, filler
New lineup:
Nash
Allen
Pierce
Green
Howard
OK, tear it apart, but you know it's entertaining! That would be the best shooting backcourt in history (Nash + Allen), Howard is the type of center that would allow Jeff Green to operate at the "4" spot. Our defense would still be top notch (look at what Orlando does with Howard) and our offense would be pretty amazing...
