Sitting atop the NBA standings is new territory for the Memphis Grizzlies. Just getting off to a fast start is unusual.

The Grizzlies, who usually stumble out the gate, are a league-best 13-3. They've never had a better record after the first 16 games of the season. They were 11-5 in 2005-06 and 10-6 last season.

Coach Lionel Hollins and his Grizzlies list several reasons for the great start, ranging from scheduling to preseason preparation to better chemistry.

Guard Mike Conley credits a different mindset at the start of training camp for the turnaround. He says the Grizzlies already were in shape and in mid-season form mentally for their season-opener.

So far, so good.

The Grizzlies are the NBA's best after a 108-98 overtime win over Phoenix on Tuesday night.
