Playing time is earned in practice. And, you then have to produce in the actual games.
Crump started Texas' first game of the season and her first shot was a 3-pointer (made). That surprised a lot of Texas fans but it showed how much faith Vic had in her hard work and talent. She went on to start the next 4 games before getting injured and not returning to the court until early January.
Competing for minutes against other shooting guards and forwards (not including Center and PG as she can't play those positions), her 17.5 minutes per game trailed only Booker (32.5), Lee (31.7), and Carlton (19.4). She was also competing for minutes against senior forwards Ashton Judd and Teya Sidberry. Crump getting more minutes means taking away minutes from those players I listed. Plus, her foot injury probably had somewhat of an impact on how many minutes she played in order not to re-aggravate it.
Wish she'd never have gotten injured. Things could have turned out a lot different for her as she was averaging 24 minutes a game and 13 ppg prior to getting injured.
