Maponga was the District 6-5A Defensive Player of the Year his senior year of high school. He totaled 71 tackles, including 5.5 sacks and also had over 20 quarterback hurries. He redshirted his first year on campus. However, in 2010, he made an impact as soon as he saw the field. Maponga started 12 games and tallied 32 tackles (three for loss), 2.5 sacks, and one forced fumble. He was named second-team All-Mountain West.
Maponga bettered his production in 2011, as he was named first-team All-Mountain West. He became one of four players in the nation to rank in the top 10 in forced fumbles and top 20 in sacks, where he recorded five and nine respectively. Maponga topped TCU in tackles for loss, sacks, forced fumbles, and fumble recoveries. He forced five fumbles which were the most by a Horned Frog since Jerry Hughes led the nation with six in 2008. In 2012, Maponga missed two games to injury, but was still named first-team All-Big 12. He registered 26 tackles (6.5 for loss), four sacks, and two forced fumbles.
Compact, powerful build with what appear to be long arms for his height. He has a solid punch with consistent hand placement. He's an aggressive player and can work his hands. Locks out his arms in order to create separation from his blocker. Physical. When he times up the snap well, he has a good first step. Showcases some flexibility.
Doesn't have ideal height. Very inconsistent off the snap, at times will be the last one moving. Will get upright off the snap. Has a initial burst, but fails to find an extra gear in his pursuit to the backfield. Doesn't look comfortable in space. Struggles to counter when the offensive lineman gets his hands on him or hits him with a cut block.
Maponga showcases power, hand usage, and a nice spin move. However, his game is highly inconsistent at this point, and revolves mostly round flash plays. Where is he is selected will be based upon a coaching staff's confidence that he can develop into a consistent player.
Future Hall of Famer
A once-in-a-generation type prospect who could change how his position is played
An impact player with the ability/intangibles to become a Pro Bowl player. Expect to start immediately except in a unique situation (i.e. behind a veteran starter).
A quality player who will contribute to the team early on and is expected to develop into a starter. A reliable player who brings value to the position.
A prospect with the ability to make team as a backup/role player. Needs to be a special teams contributor at applicable positions. Players in the high range of this category might have long-term potential.
A player with solid measurables, intangibles, college achievements, or a developing skill that warrants an opportunity in an NFL camp. In the right situation, he could earn a place on a 53-man roster, but most likely will be a practice squad player or a camp body.
