PHILADELPHIA (ET) — The most revealing part of UCLA’s NCAA Tournament opener wasn’t a single highlight, but how quickly a reshuffled rotation found a new center of gravity. With Tyler Bilodeau held out as a protective measure because of soreness in his injured right knee, xavier booker moved into the starting role and produced an across-the-board performance in a 75-71 win at Xfinity Mobile Arena. The result did more than stabilize one night’s lineup; it sharpened the stakes of what comes next.
What happened: a short-handed UCLA finds production at center
UCLA’s win came with an immediate adjustment: Bilodeau didn’t play, and the minutes and responsibilities in the frontcourt shifted. That shift became the story because the fill-in didn’t merely “hold the fort. ” Booker delivered 15 points, eight rebounds and four blocks. Coach Mick Cronin noted the eight rebounds matched Booker’s season high, while Booker pointed to the blocks when asked about his greatest impact.
The body of work mattered as much as any one stat. UCLA guard Trent Perry emphasized Booker’s activity level, describing it as “huge” in a game like that. Booker’s impact showed up in multiple ways: rim protection, rebounding, and staying connected defensively to prevent dribble penetration at the basket. In a tournament setting where single possessions can swing outcomes, that combination can function like a force multiplier.
Xavier Booker and the hidden value of “motor” when the rotation tightens
The night also reframed an underlying theme Cronin has stressed about Booker: intensity and pace. Cronin has described “motor” as the hardest thing to teach, a point he has made while discussing Booker’s development. In the opener, the “motor” discussion moved from practice emphasis to live evidence—Booker wasn’t just present; he was active, engaged, and influential on sequences that decide close games.
Booker’s own comments pointed to the mental mechanics behind that activity. He said he found out early in the day he would start, then leaned on his normal pregame routine—listening to music—to calm himself. He also described a tendency to get too excited and overthink, and framed his approach as locking in on what he had to do rather than overprocessing. That matters because it suggests the performance wasn’t purely opportunistic; it was connected to a repeatable routine and a clear internal checklist.
From a tactical perspective, UCLA’s willingness to “throw it to him, ” as Cronin put it, indicated trust on the offensive end. Booker was especially dominant after halftime, making 4 of 5 shots in the second half. He scored UCLA’s first two baskets of the half on a jump hook and short jumper, then punished a small lineup with a transition lob dunk and later added a 3-pointer. Those details tell a specific story: UCLA didn’t only survive possessions; it found ways to generate varied frontcourt offense through Booker.
Why this matters now: Bilodeau’s uncertain status and UCLA’s frontcourt math
Bilodeau’s status for Sunday’s second-round game against UConn remained uncertain after he was held out. That uncertainty places a spotlight on the Bruins’ options and the trade-offs they face. One clear benchmark is production: Bilodeau averages 17. 6 points, while Booker averages 6. 9 points and 3. 3 rebounds over a season in which he has made 25 starts but was recently moved to the bench while still playing the most minutes of any UCLA bench player.
In the opener, Booker and backup Steven Jamerson II combined for 17 points—Booker’s 15 and Jamerson’s two—matching Bilodeau’s scoring average in aggregate. That doesn’t mean one game replaces a season-long role, but it does show a path for UCLA to approximate its usual offensive baseline even if Bilodeau can’t shoulder his typical workload.
The other part of the equation is defensive identity. Cronin joked with Bilodeau that UCLA might have been better defensively without him, and Booker’s locked-in rim protection and on-ball activity threatened to turn that wisecrack into a real tactical question. If UCLA’s next opponent forces the Bruins to choose between offensive continuity and defensive ceiling, xavier booker has now provided evidence he can contribute on both ends when his role is clearly defined.
Expert perspectives: Cronin, Booker and Perry on what actually changed
Three voices around UCLA offered the clearest breakdown of what shifted with Booker in the lineup.
Mick Cronin, Head Coach, UCLA, highlighted rebounding and offensive usefulness in blunt terms. He pointed to the eight rebounds—matching a season high—as a major positive, and he emphasized a need to involve Booker offensively: “We threw it to him. We need that. He’s an offensive player. He can play on that end. ”
Xavier Booker, Center, UCLA, framed his priorities as both self-awareness and role clarity. He described staying within himself and made clear what the staff wants: rebounding, defending, and blocking shots. He also signaled that defense is the core expectation he is embracing: “Just being able to defend, ” he said, calling it the main thing both coach and player want.
Trent Perry, Guard, UCLA, underscored something coaches often value more than any one stat line: consistent activity. He said seeing Booker’s activity “especially in a game like this” was “huge. ” That’s a telling assessment because it points to effort translating under tournament pressure, not just in routine minutes.
The ripple effect: what UCLA can carry into the UConn matchup
There is no public certainty embedded in the current picture—Bilodeau’s status is described as uncertain, and UCLA’s next game is against UConn on Sunday. But the opener created a concrete takeaway: UCLA can adapt its frontcourt usage without collapsing its identity. The game showed a version of UCLA in which the center position can drive the defense (four blocks, consistent rim protection) while still being a credible offensive option when the team commits to feeding him and exploiting matchups.
The bigger question is whether this can be repeated when scouting tightens and physicality rises. One contextual note remains relevant: Booker’s offensive uniqueness is described as giving him a high ceiling, while his defense has been criticized as lagging “especially in more physical games. ” That tension is now central to UCLA’s immediate future. If Booker sustains the defensive focus and motor that appeared in the opener, the Bruins gain more than emergency insurance—they gain lineup flexibility and a second way to win possessions.
For UCLA, the most important development may be psychological as much as tactical: a player who acknowledged overthinking found a way to settle into a demanding start and deliver. If Bilodeau remains limited or unavailable, xavier booker has already shown what “next man up” can look like at a tournament level.
Sunday will test whether the opener was a one-night answer or the beginning of a new equation—can UCLA keep its March momentum if it needs xavier booker to anchor the paint again?
