The one thing that surprised the talented 2010 quarterback was how many campers made the one day appearance in St. Louis.
"There had to be over 500 campers there on one high school football field, it was crazy," Marler told InsideMizzou.com. "There were a lot of great athletes there."
Campers endured a rain delay Sunday at the camp, something that caused all the campers to get limited numbers of throws and reps.
"There were so many people there it made it difficult for one person to get a lot of reps," Marler said. "I got to throw maybe five passes. There were 50 receivers in each line and about four lines."
Marler, a 6-foot-2, 230-pound junior to be from Potosi Missouri, got the opportunity to visit with a couple of the Tiger Coaching Staff.
"They were really nice," Marler said. "I got a chance to talk to Coach Yost and a couple of others."
Marler grew up a Tiger fan and was happy to participate in his first Mizzou camp.
"It was great," Marler said. "It's always good to let the coaches know who you are."
Marler through for over 1,200 yards last fall as a sophomore.
