A wise man once said the only constant is change.

He must have been talking about the point guard position on the Penn State women's basketball team.

All season long, junior Katrena Carr and sophomore Ashley Luke have battled for the starting spot, and both have had their fair share of struggles running the Lady Lions' offense.

The point guard carousel continued Sunday afternoon, but this time the results were a bit more favorable, as Carr turned in her best performance of the season, leading the Lions to a 97-49 drubbing of Michigan State.

The season began with Luke as the starting point guard and Carr as the shooting guard. But Kelly Mazzante's deadly shooting touch left Penn State women's basketball coach Rene Portland with no choice but to insert the freshman into the starting off-guard spot. Luke and Carr traded starts at the point early on but Carr had supplanted Luke by the start of the Big Ten season.

Then last week, the carousel was in full swing again, as Luke returned as the starter against Indiana.

But just as quickly, Carr was reinserted back into the lineup, almost by default. Luke suffered a broken finger on her non-shooting hand early in the Indiana contest, and the team was uncertain if she would even play Sunday at all.

"Trena was in a very difficult position tonight," Portland said after the game. "She was ready for 40 minutes, and I thought she ran the team very well."

Carr ran the team exceptionally well for a team-high 32 minutes against the Spartans. She scored 12 points on 5-9 shooting and handed out a career-high eight assists, but most importantly, had nary a turnover, the statistic that has been the Achilles heel of the Penn State backcourt all year.

Carr also played with intensity at the other end of the floor.

"I had a few mistakes, a few bad shots that I might have taken," she said. "But I made up for it on defense."

Although Sunday's outcome was never really in doubt (the Lions scored the game's first 12 points and led by 27 at the half), Carr's steady hand at the point was encouraging to Portland and the Lions.

"She really listened to what we needed to do tonight," Portland said.

While there is no way of knowing how long she will remain the starter, Carr said she is comfortable with either role.

"I just try to do the best I can, whether I'm starting or not," Carr said. "And wherever she (Portland) puts me in, do what is best for the team."
