The Milwaukee Bucks collapsed in the second half against the Toronto Raptors, losing 121-107 on Friday and dropping to 1-8.

Milwaukee has lacked consistency this season, failing to string together impressive quarters. The Bucks' strong first half gave them a nine-point halftime lead.

Toronto flipped the script in the second half. Back-to-back 30-plus-point quarters and 27 points from RJ Barrett and Alijah Martin powered the Raptors to a double-digit win.

Bucks guard Tyler Herro echoed Jaime Jaquez Jr.'s comments from Wednesday's loss to the Boston Celtics. He said the team is trying to sustain good play for 48 minutes.

Connective passing, fast-break points and crisp defensive rotations have led to 30-point quarters, but they haven't replicated it often. Herro focused on Milwaukee's defensive collapse and playing in the half-court more often than in transition.

RJ Barrett and second-year forward Collin Murray-Boyles dominated the third quarter. Barrett scored six points, grabbed three rebounds and dished out three assists; Murray-Boyles scored seven points, grabbed three rebounds and recorded two steals.

The second-year forward swatted lazy passes, turning defense into offense. Milwaukee defenders died on screens, letting Barrett dribble into mid-range pull-ups.

Coach Taylor Jenkins' defense was a step too slow in half-court and in transition. The Bucks have allowed multiple 30-point quarters in the past four games, including a season-high 48 points by the Cleveland Cavaliers last Saturday.

Herro tried to quell the Raptors' surge with 10 points. He consistently got two feet into the paint and converted highly contested floaters.

The 6-foot-5 guard said Milwaukee had to take the ball out almost every single time in the third quarter and often faced a set defense.

Its inability to generate turnovers like Murray-Boyles did for Toronto, led to minimal fast-break points. The Raptors had 12 steals and forced 21 turnovers against the Bucks.

Herro said it's tough to beat any team when they have 16 more possessions. More possessions lead to more opportunities, and playoff teams capitalize on them efficiently; that's what separates a good team from a rebuilding team.

Milwaukee is acclimating to a new coach and roster without Giannis Antetokounmpo at its core. A new roster and staff going through trials and tribulations is expected, but a five-game losing streak reflects bad habits becoming the norm.

Herro's carrying the scoring load, averaging 22.3 points, but Jenkins must make defensive adjustments to create more transition opportunities for quality offense.
