As ugly as the 2007 season was, one of the undeniable bright spots was the emergence of rookie inside linebacker David Harris. From the beginning of the season, Harris was in the linebacker rotation, but it wasnt until week 8 against the Buffalo Bills when he stepped in for the injured Jonathan Vilma that he began to shine. In his first start, he logged 17 tackles (10 solo) and a sack, which seemed impressive until the next game, where he followed up with a 24-tackle (20 20! solo) effort. Although his monster tackle numbers leveled off a bit, he still wound up leading the team by the end of the season, notching 127 according to the NFL and 117 according to the Jets staff. Jets stat master Randy Lange notes Harris also led the Jets with 9.5 tackles for loss/no gain. Of course, being a Jet in a losing season, Harris remarkable rookie campaign failed to attract any national attention. When it came time to award NFL defensive rookie of the year, the honor went to linebacker Patrick Willis of the San Francisco 49ers, who also had a brilliant season, leading the NFL in tackles with 174. Harris got scant consideration, let alone an actual vote Carolinas Jon Beason came in second with two votes. Source: TheJetsBlog
The reason is because he plays for the Jets. Whenever they have a half-decent player their fans shout and scream about how great they are and piss everyone off.
Maybe if the jets had 11 david harris on defense they would have a good defense and on offense if they had good players on offense they would be good.
