KELLER — As Keller inches closer to perhaps repeating as District 4-5A champions, guard Kyle Tanner said his team has cemented its place as a defensive-minded squad.After a 3-point barrage helped the Indians to an early lead Tuesday night, it was a stifling defensive front that kept Southlake Carroll at bay in a 78-70 win at Keller High School. The victory keeps Keller (19-4, 9-1) in the driver’s seat with four district games remaining, while Carroll remains on the outside looking in for the final playoff spot.“We’ve talked about that, playing in front or with the lead and wearing teams down,” Tanner said. “Even though we were shooting the ball well, we were talking about how they got too many rebounds and too many easy baskets. We changed that in the second half.”Through three quarters, Carroll (10-9, 4-6) was just 16 of 56 from the field and 2 of 13 from 3-point range. “I thought our defense was really good tonight,” Keller coach Randall Durant said. “And what that does is make our offense crisp. We shot the ball really well and you’ve got to do that against a team fighting for a playoff spot like they are.”Brock Anders led Keller with 22 points, including three 3-pointers in a decisive 16-5 first quarter run. The Indians seized the lead at that point and Carroll never got closer than six points. Nolan Taylor added 21 points and Tanner finished with 19.Four players were in double figures for Southlake, including Cole Partyka who led the Dragons with 16 points.
