On September 29, Ihenacho made the only blocked punt in a win against UC Davis.[1] Following the blocked punt, quarterback Adam Tafralis made a 47-yard touchdown pass.[5] Ihenacho made a season-high seven tackles on October 12 against Hawaii and forced a fumble in that game as well.[1] San Jose State ended 2007 with a 5-7 record (4-4 in Western Athletic Conference games).[6]
In 2008, ESPN ranked Carl and Duke Ihenacho as one of the top ten brother combinations in college football for being among the top defensive players in FBS football.[7] By mid-October 2008, Duke led the FBS in interceptions.[3] In both the October 11 game against Utah State and October 18 game against New Mexico State, Ihenacho scored a 43-yard touchdown off an interception. Ihenacho's two interceptions in the Utah State game marked the only such time in the 2008 season. Ihenacho played as a linebacker in 2008 and was a first-team All-Western Athletic Conference (WAC) selection.[1] San Jose State finished 2008 one game up from 2007, 6-6 (but still 4-4 in WAC).[8]
However, San Jose State finished the 2009 season 2-10 (1-7 WAC). In 2009, Ihenacho made 89 tackles, the second-most in the team that year, and tied his individual game high of 12 on October 10 against Idaho and November 21 against Hawaii.[9] San Jose State football coach Dick Tomey retired after 2009, and Mike MacIntyre became the new head coach.[10] In MacIntyre's first season, the Spartans finished 1-11 (0-8 WAC).[11] Ihenacho played only in two games of 2010 before a season-ending injury.[12]
2011 was a better season for the San Jose State Spartans, who finished 5-7 (3-4 WAC).[13] Ihenacho made 73 tackles in 2011, the third-most in the team, and led the team in deflected passes with six. Ihenacho made his third career touchdown on October 1 with a 20-yard fumble return against Colorado State.[1] That was also the first fumble returned for a touchdown by a San Jose State player since 2004.[14] In four games, Ihenacho made 10 or more tackles, including a season high 11 each against Idaho and Utah State.[1]
On October 14, 2011, San Jose State rallied in its homecoming game to beat Hawaii 28-27. ESPN carried that game as part of College Football Friday Primetime. With San Jose State down 27-20 in the fourth quarter, Ihenacho recovered a blocked point after touchdown and took the ball to the end zone for a defensive two-point conversion. San Jose State won despite five turnovers.[15][16]Geico nominated Ihenacho's conversion as the company's Play of the Year.[17] Ihenacho earned his third first-team All-WAC selection in 2011.[18] In December 2011, Ihenacho graduated from San Jose State with a B.A. in communication studies.[19]
Professional career
Pre-draft
Ihenacho was considered one of the top strong safeties in the 2012 NFL Draft.[20] and was projected as a 5th round pick.
Ihenacho signed with the Denver Broncos as an undrafted free agent following the 2012 NFL Draft on April 28, 2012.[23] Ihenacho played all four games of the 2012 preseason and made seven tackles during the preseason.[24]
The Broncos signed Ihenacho to the practice squad on September 1 and activated Ihenacho from the practice squad on September 29, 2012.[25][26] On October 11, 2012, the Broncos released Ihenacho. They later signed him back to the practice squad on October 13 and to the active roster again on November 1. Ihenacho made one assisted tackle in his second game of the season, November 4 (Week 9) in a win over the Cincinnati Bengals.[24] On November 13, 2012, he was waived by the Broncos.[27] Three days later, the Broncos re-signed Ihenacho to the practice squad.[28]
In the 2013 offseason, Ihenacho began turning heads, showing very good cover skills and run stopping abilities. In the first released depth chart, Ihenacho climbed all the way to the number two spot for strong safety, pushing Mike Adams for the starting job. In the Broncos' first 2013 preseason game against the San Francisco 49ers, Ihenacho was in with the starters and led the team with 7 tackles, one being for a loss, and also had a forced fumble, which Rahim Moore recovered.
On September 5, 2013, Ihenacho started his first NFL game at strong safety against the Baltimore Ravens. He recorded 11 solo tackles and had one assisted tackle in Denver's 49-27 win.
