The elephant in the room is as big as a float in the Macy’s Thanksgiving Day Parade. Geno Smith may be absorbing the verbal body blows from Monday morning quarterbacks in the wake of another statistically subpar performance, but his supporting cast would probably get bounced in the preliminary rounds of “America’s Got Talent.” The Jets have surrounded their rookie QB with the old, the broken down, the injury-prone and the mediocre (at best) at the skill positions. Smith’s weaponry on Sundays: water balloons. Rex Ryan conceded Monday that Smith’s cringe-worthy stats “(don’t) paint the whole picture” due to myriad factors. “There’s a reason,” for Smith’s 22 turnovers, the coach maintained, that go beyond just one player. Ryan is right. Those among the Jets’ brain trust can slide a mirror in front of their collective faces to find the culprits for the lack of offensive firepower on the roster. Smith is far from innocent, but the organization’s decision to apply Scotch Tape to seal the skill-position cracks in the offseason has precluded the offense from gaining traction this season. They went to Walmart for repair supplies. They should have called the Property Brothers. Jeremy Kerley’s 28 receptions are the fewest for any team’s leading receiver. He’s on pace for a grand total of 505 yards. Santonio Holmes, contractually obligated to remind people of his Super Bowl MVP trophy as often as possible, has followed up his nightmarish, injury-marred 2012 with a nightmarish, injury-marred 2013 (13 catches, 326 yards, 1 touchdown). Stephen Hill, who has quietly been playing through knee and foot injuries, has not had a catch in the past three games.
