Mayle started his college career as a basketball player at Shasta College where he averaged eight points per game and once won a dunk contest.
"I started off playing basketball, but one of my coaches told me I would be a better wide out than a point guard, so I took that advice."
After playing basketball at Shasta College, Mayle transferred to Washington State where he started playing football. In his first season at Washington State, Mayle caught 42 passes for 539 yards, including seven touchdowns.
Mayle had a high number of dropped passes in college and was criticized for the number. He was asked about his hands.
"I believe the scouting reports are wrong," Mayle said. "I like to get up the field right away and sometimes take my eye of the ball."
He was asked what he intends to do to improve catching the ball.
"It’s a humbling experience," he said. "It lets me know there’s something wrong with my game and that I need to improve."
Dane Brugler of NFLDraftScout.com compared Mayle in some ways to Louisville’s DeVante Parker.
"H-back/tight end by some scouts, (Mayle) showed more natural receiving traits as a senior and although he’s not quite as gifted as Louisville’s DeVante Parker, Mayle is a lesser talented prospect in a similar mold," Brugler said. "It’s clear he’s still learning the tricks of the trade and his passion for football needs to be addressed, but Mayle is an easy player to get excited about with his size, athleticism and the upside his talent suggests - projects as a NFL starter in year two."
