(AP) -- A four-guard attack is largely responsible for No. 13 Missouri's best start since 2006 under new coach Frank Haith.

A not-so-big man off the bench has done his part, too.

Senior Steve Moore had trouble keeping up with the running game and avoiding foul trouble last season.

He lost weight during the offseason and at 6-9 and 267 pounds, is still the largest player on the roster.

He has become more of a contributor.

Moore averaged 11 minutes and two points last season.

He's playing 15 minutes this year with a 4.7-point average.

He was a big factor in a victory over California with a career-best 10 points, three blocked shots and three assists.
