Davies, who was suspended for the rest of the season last week for violating the school's honor code, sat on the bench in street clothes during the Cougars' gritty 64-58 Mountain West Conference quarterfinal win over the Horned Frogs on Thursday afternoon at the Thomas & Mack Center.
Hill noticed Davies' absence.
"They're a much different team without Davies," Hill said. "He's a big inside presence, brings a lot of attention, which also gets a lot of attention off the key player."
BYU guard Jimmer Fredette scored 33 and 38 points, respectively, in the Cougars' two regular-season victories over TCU. On Thursday, though, he was limited to 24.
Fredette was asked about how his team has had to "reinvent" itself in light of Davies' suspension.
"I don't think we have to necessarily reinvent anything," Fredette said. "We still have guys on this team that can play. They're still going to play the same way. I don't think that we have to necessarily change the way we play to be a better team."
TCU coach Jim Christian said his players weren't necessarily more confident knowing Davies wouldn't be playing in the game.
"I don't think it had anything to do with him, to be honest," Christian said. "I think our guys would have been confident regardless of who stepped on the floor."
Christian reiterated that the No. 8 Cougars still have plenty of weapons.
"I think BYU is a great basketball team. They're one of the top-10 teams in the country for a reason," he said. "You're not a top-10 team because you have one or two great players. They're adjusting (without Davies).
"I thought the only obvious emphasis is they don't score the ball on top of the rim as often as when Davies is in the game. It also makes them a tougher team to guard on the perimeter. With (Charles) Abouo and (Noah) Hartsock, you have guys that can hit 3s."
FREDETTE IN FINAL FIVE: Fredette is one of five finalists for the Bob Cousy Award, emblematic of college basketball's top point guard, along with Cleveland State's Norris Cole, Duke's Nolan Smith, Wisconsin's Jordan Taylor and Connecticut's Kemba Walker.
ANOTHER RECORD FOR FREDETTE: In the first half, Fredette broke the school's all-time, single-season scoring record. Devin Durrant previously held the mark with 866 points in 1983-84. Fredette now has 888 points this season.
COLLINSWORTH'S STATUS: Late in the game, freshman guard Kyle Collinsworth fell hard while driving for a layup. His head slammed on the floor and he remained down for a few moments before going to the free-throw line.
Collinsworth missed a game earlier this season after sustaining a concussion. He should be ready to play tonight when BYU faces New Mexico in the MWC semifinals.
NOTABLE: BYU now has 17 consecutive victories over TCU. ... The Frogs are 0-20 when scoring less than 70 points this season. ... Every BYU starter recorded at least two assists.
