Maponga, a three-year letterman for the Horned Frogs, is projected by many draft experts to be a third or fourth round selection.
The 6-foot-2, 265-pounder played in ten games in 2012 recording 22 tackles and 2.5 sacks while missing two games due to an injury. Despite the lowest totals in his career, Maponga was still named second-team All-Big 12 by the Associate Press.
Maponga burst onto the scene his freshmen year as he recorded 32 tackles and 2.5 sacks and was named a freshman All-American.
He became a household name his sophomore season with a huge season that saw him record 55 tackles, 9 sacks, 13.5 tackles for loss, 5 forced fumbles and 2 fumble recoveries. He was one of just four players to rank among the top ten in forced fumbles and top twenty for sacks. He was named a first-team All Mountain West selection.
Two sophomores are expected to compete for the left defensive end position; James McFarland and Josh Carraway. Both players were among the sixteen true freshmen who played for the Horned Frogs in 2012.
With his decision to leave early, Maponga joins Frogs' receiver Josh Boyce, who elected to enter the draft last week.
