GAINESVILLE, Florida (Ticker) -- Florida knows how to share the ball. Now Billy Donovan will share his feelings on its defense.

Even without their top guard, the eighth-ranked Gators enjoyed a near-flawless offensive effort, rolling past Montana State, 112-73, for their 13th straight season-opening win.

Playing unselfishly, the Gators (1-0) set opening day records for points, shooting percentage (65.7) and 3-pointers made (11) while holding a 47-17 advantage in rebounding.

Gators starting guard Anthony Roberson completed a three-game suspension for an unspecified violation of school policy. He also missed a pair of exhibition wins.

Roberson returns Friday night against third-ranked Arizona. By then, Donovan hopes his team will have corrected some errors, specifically defending the 3-pointer, getting back in transition and helping out in the block.

"When I go back and look at the film, there is going to be a lot of disappointment in certain areas of our defense," said Donovan, who recorded his 150th win at Florida.

Florida also had 31 assists, its second-highest total since Donovan took over as coach eight years ago. Christian Drejer led the way with 11.

"Right now, it's not really about who is scoring," said Drejer, a 6-9 sophomore forward from Denmark. "It's about who happens to be the right guy in that place and time."

David Lee was in the right place and time most often, scoring 20 points. Drejer added 19, Matt Walsh 18 and Bonell Coles 14.

The Gators used a 16-0 run to open a 23-7 lead 7:46 into the game. They built a 37-14 cushion on a driving layup by Drejer with 7:17 left in the first half and led by at least 19 the rest of the way.

Florida shot 70 percent from the field (23-of-33) in the first 20 minutes and finished the game at 66 percent (44-of-67). The starting five of Drejer, Lee, Walsh, Coles and freshman Ryan Appleby combined to go 31-of-41 from the field.

"It's one of those games you felt like every time they shot the ball it was going in," Montana State coach Mick Durham said. "It's one of those nights where a lot of guys were feeling it and this is a team tonight that didn't have Roberson."

Durham didn't see many problems with Florida, but he knows his team needs to improve, particularly off the boards. The Bobcats (2-1) had 17 rebounds, four more than the Gators grabbed on the offensive end.

"I think we need to find a rebounder," Durham said. "That obviously is the glaring stat."

The Bobcats played well in a few areas. They were 10-of-20 from 3-point range, committed only 12 turnovers while forcing 17 and held a 20-15 advantage in fast-break points.

Matt Towsley and Frank Brown scored 12 points apiece for Montana State, which shot just 41 percent (26-of-63).
