And here we are at #2, the number that gave Raider fans so much hope and then so much indigestion. #2 was most famously worn by a certain LSU product that reminded us all of Pizza the Hutt and took all the Raiders' money and gave it directly to his drug dealer. We will not mention his name; you all know who he is. But he wasn't the last to wear the #2, nor was he the best.
Who wore it best: P Leo Araguz (1996-99)
Leo Araguz was a fine punter for the Raiders in the late nineties, setting a record which stands to this day for punts in a game with 16 in a 7-6 win over the Chargers in 1998. He is the fifth-leading punter in Raiders history, with 12,023 yards on 280 punts. He attended Stephen F. Austin State and last played in the NFL in 2006 with Baltimore. According to his Wikipedia entry, he is currently playing for the Rio Grande Valley Sol of X-League Indoor Football, which is apparently a real thing that exists.
Who wears it now: Nobody
Who wore it most recently: QB Terrelle Pryor (2011-13)
Pryor has the distinction of being Al Davis' last ever draft pick before his death, taken in the third round of the 2011 supplemental draft. He originally wore #6 but switched to #2 during the 2013 preseason. He battled Matt Flynn for the starting QB job that year, but it turned out neither of the two were very good. Pryor was fast, though, and set a record for longest rush by a quarterback with a 93-yard run against Pittsburgh. His departure thankfully led to the drafting of Derek Carr.
