Powell said he considered transferring to San Diego State in his hometown after Howland was fired, but he didn't want to have to sit out a year.
"I've really been working on my shot," said Powell, who went 8 of 13 from the field, including two 3-pointers. "I haven't been shooting the 3-ball the way I wanted to. I've been getting up extra shots at practice and on my own. I feel like it's really paying off. I'm really confident in my shot and it's going in."
