Strangely if you put where David was drafted into contention, he seems to be much better relatively. He was eight years ago, a fourth round pick! Comparing him to the other fourth rounder QBs of the 2002 to 2010 period, he is by far the best.
One other Quarterback was selected in the 4th round, 2002
Rohan Davey, of LSU
His career stats with NE and then Arizona were with 7 games played (from 02-04 with NE), 8 for 19 for 88 yards with no Tds nor INTs, and ran 6 times for -6 yards with no fumbles
Seneca Wallace, as QB/WR
In 2003 and 2004 he recorded no stats, and from 2005-present, he is overall 396 for 656, for 4240 yards, 29 Touchdowns, and 16 INTs. He was sacked 49 times overall, and rushed 61 times for 223 yards and one touchdown in his career to this point. He is starting in Cleveland and started quite often in Seattle. He was not a QB always though! He was actually a rather good 3rd or 4th WR.
Selected by Carolina, he sadly never played at all in his one season, 2005
Strangely no quarterbacks were selected in the fourth round in either 2007 or 2008
Following the three year rule, the 2009 and 2010 drafts were not reviewed.
