The 6-foot-4, 202-pounder passed the eyeball test with strong throws throughout the day and worked among the top quarterback group late in the camp.
Muehlstein felt he did well on the day.
"I thought I did good. I came out to compete to see how I stack up against everybody else and I thought I did good," he said.
As a quarterback there's always room for improvement and for Muehlstein, he feels he needs to improve his consistency moving forward and fine tune his mechanics a little.
"My accuracy and just being more consistent," Muehlstein said of what he needs to improve. "I need to get my shoulder more turned to the target. All of these coaches have been through it and know what they're talking about. I took away some good pointers from today."
Before he made his way to Las Colinas, Muehlstein and his family visited TCU Saturday morning to catch the Frogs last practice of the spring.
"I thought it was good, it was just a final tune up of the spring," he said of TCU's practice. "It looked good."
While Muehlstein continues to work on his game, he's also eyeing some fellow recruits to help build the Frogs' already impressive 2014 class.
"I talked to Connor (Mayes) today and I've talked to Jimmie Swain to before," he said.
