Somewhere along the way a segment of the Jets fan base morphed into sad self-loathing people who frankly don’t deserve a Super Bowl team. The silent majority of long-suffering fans are sensible fully appreciative that Rex Ryan’s teams have delivered some indelible moments the past few years and aware that 2013 will be a rebuilding season. It’s too bad that the obnoxious minority reared its ugly head by voicing displeasure toward one of its own during an intrasquad scrimmage over the weekend. A few thousand Jets “supporters” hid behind their First Amendment rights when booing Mark Sanchez after an interception in practice. Antonio Cromartie rightfully called it “bull crap”. . .and he wasn’t alone. It was embarrassing behavior that ran contrary to Ryan’s mission to build excitement entering 2013. “Hey you’re preaching to the choir” Sanchez told the Daily News on Monday about the absurdity of booing players in practice. “You heard what Cromartie said. Cromartie was pissed. Cromartie’s like ‘What are you talking about? You’re going to come here and boo? For what? Then don’t come.’ A lot of guys feel like that.” Fans have been understandably frustrated with Sanchez’s penchant for turnovers in the past two seasons but this was a pathetic display. It was a free scrimmage. In August. Although Ryan admitted on Monday that fans “can do whatever they want” he underscored the need to look beyond the team’s recent mistakes with a positive eye toward the future.
