Basketball followers call a player making every shot “being in a zone.” But you may have to use a different term to describe what Carroll’s Gretchen Morrison delivered last week.Morrison entered a different dimension. She went 15-of-17 from three-point range – yes, you read that right – in Carroll’s 26- and 40-point blowout victories over Richland and Justin Northwest.Morrison was 8-of-10 from long distance against Richland and 7-of-7 against Northwest. She scored 34 and 31 points respectively. Head coach Teri Morrison – no relation, but she probably should claim it, just because – said she’s never seen anything like that in her years of coaching.“She’s the best shooter I’ve ever coached,” Morrison said. “People have been getting after her, but we’ve started to do more by getting her shots off the gap. [Point guard Kennedy Leonard] has done a great job of finding her.“The other thing is that Gretchen is just not hitting these shots from the corner. She’s all over the floor and getting looks. And really, that’s what she needs at the next level.”Gretchen Morrison has signed with Jacksonville State out of Alabama. She has made 76 three-point baskets this season entering Tuesday’s game.Meanwhile, Carroll (24-4, 11-0 in District 4-5A) has wrapped up a playoff berth and could have clinched a tie for the No. 1 seed had it won at Keller on Tuesday. That win and beating Keller Fossil Ridge on senior night Friday would give the Lady Dragons the outright championship. The program has won 22 consecutive district games before the Keller contest. “We’re in a good place right now,” Morrison said.Defensive concernsTeri Morrison calls her squad a good defensive team but not a great one. The Lady Dragons have been aggressive but haven’t kept opponents out of the lane.If Carroll is going to make a deep postseason run, this group is going to have to change that.“The concerns I have are that we’re allowing too much penetration in the paint and to the rim,” Morrison said. “We have to clean that up. In our four losses, we’ve gone against some really physical teams. We’re not in the position. We need to be able to stop that. We’re letting them get to the free-throw line too much. We have to keep people in front of us.”“The other thing we have to do is start doing a better job of getting to the rim and shooting free throws. These are things we have to work on for the rest of the regular season.”NotableSophomore post Anna Hurlburt did not play Friday against Northwest because of a non-disclosed injury, Morrison said. However, Morrison said she expected the team’s third-leading scorer play Tuesday at Keller. Hurlburt did play against Richland but saw limited minutes … Should the Lady Dragons go on to win the district championship, they would earn the top seed in 4-5A and play the fourth-place team in 3-5A. Currently, that looks like a battle between Weatherford and North Crowley. Carroll beat Weatherford in the bi-district round last year, 78-38.
