The easy answer for today's days until post would be last year's Big Ten Linebacker of the Year Mike Hull. But the number was worn right before him by the unrelated same-name linebacker often affectionately known as Hullstache.
Josh Hull walked on at Penn State in 2005, having been a three- year starter at Penns Valley in Spring Mills, PA. He redshirted his first year in Happy Valley before seeing time his first two seasons of eligibility, predominantly on special teams. It wasn't until his redshirt junior year, 2008, that he started at Penn State; Hull was able to take advantage of Sean Lee's ACL tear and started all 13 games in that Big Ten Championship season, ending the year second on the team in tackles (to NaVorro Bowman). That same year, he was also named an Academic All-American and was named the first ever Big Ten Distinguished Scholar.
As a senior in 2009, he did even better, logging 116 tackles (45 solo), 2 sacks and 2 interceptions alongside fellow LBU standouts Sean Lee and Bowman. He too was drafted, but not as high as his former teammates; he narrowly missed being named Mr. Irrelevant, going in the 7th round with pick number 254 to the Rams, where he stayed through the 2012 season. After his three seasons in St Louis, Hull spent 2013 in Washington with the Redskins; in the 2014 offseason, he was signed and released by both the Patriots and the Jaguars.
