Just add LeBron James and — boom! — you're a title contender.

Of course, that's the long-held philosophy in the NBA, and it has played out multiple times.

So it shouldn't be a surprise in the wake of James' signing with the Lakers that Las Vegas suddenly loves L.A.

Per ESPN.com:

After news broke Sunday evening that James is headed to Los Angeles, the Westgate SuperBook reopened the Lakers at 9-2 to win next year's title.

The Lakers' odds immediately were trimmed to 7-2 after a "respected wager" quickly came in on the Lakers, according to Westgate assistant manager Jeff Sherman.

Only the two-time defending champion Golden State Warriors have better championship odds than the Lakers at the Westgate. The Warriors are odds-on favorites at -110 to three-peat.

The Lakers, before acquiring James, opened at 20-1 at Westgate, which has the Celtics at 7-2 as well, with the Rockets close behind at 7-1 to win it all.

Meanwhile, the Cavaliers, who opened at 30-1 in part on the presumption that James might exit, were adjusted Sunday when that became a reality. Their odds of winning a title, according to the Westgate Sportsbook: 500-1 — same as the Nets and Kings. Ouch.
