"She's rebuilt programs before," Radakovich said.
Radakovich said Smith received a five-year contract worth a total of $1.375 million.
Clemson has not reached the NCAA tournament since 2002. It has not had a winning record since going 17-12 in 2003-04.
Smith was 138-138 at UAB, but her 57-39 mark the past three years was the best mark during that span in the Blazers history. She twice made the WNIT, including after this past season's 18-13 mark.
Smith said she'll bring a hard-working, fast-paced, defensive-minded style to the Lady Tigers. "Oh, it's going to be fun," she said.
Smith also warned Clemson fans that she gets a little excited on the sidelines and often wanders onto the court to make her point. "I'm warned a lot of the times by the officials that they can't have six defenders on the floor, my arms are a little long so they want me to stay in the box," she joked. "But we will defend. We hang our hats on defense. That is what I'm all about."
