Hardy (6-foot-5, 250 pounds) earned the Big West Conference Newcomer of the Year award as a junior after averaging 10.6 points and a team-high 8.5 rebounds per game. He played in 16 games as a senior.
New Orleans Saints tight end Jimmy Graham, who played basketball at the University of Miami, had a breakout NFL season in 2011 with 99 receptions for 1,310 yards and 11 touchdowns. Pro Bowl tight ends Antonio Gates of the San Diego Chargers and Tony Gonzalez of the Atlanta Falcons also played basketball in college.
