I'd say Lakers, and not close.
If a team has Lowry and Bargnani
as its best players, I'd expect it to win 30-40 games, if everything goes well. If it starts 4-18, it's sad, but it's not stunning.
Now, a team with Howard and Kobe starting 9-13 is more ridiculous. BUT the biggest thing is that they are playing the blame game on the court and in the media. I think they might actually start fighting or demanding for trades.
