“I’m the luckiest guy in the world.” Those words came from Mark Sanchez yesterday during a 20-minute interview session — his first public words since the Jets selected West Virginia quarterback Geno Smith in the second round of the NFL Draft last week. Asked if he expects to be the opening-day starter, Sanchez, with no hesitation, said: “Of course.’’ Asked if he still views himself as the future of the franchise, Sanchez responded: “Absolutely.’’ If you’re thinking that Sanchez sounds like a guy whistling past a graveyard after midnight, you are not alone. If you are thinking there should have been a #delusional hashtag at the end of those Sanchez statements, you are not alone. But here’s some sobering news, Jets fans (look away Sanchez haters and detractors, because you’re not going to like this): The Jets’ starting quarterback in 2013 will be Sanchez. The Jets’ best chance to win however many games they might win in 2013 with their depleted depth chart will be with Sanchez at quarterback. Not Smith, who is raw and will be best-served to watch and learn for a year. Not David Garrard, who is 35 years old and hasn’t played an NFL game since 2010. Not Greg McElroy, who’s a smart kid but does not have the arm or durability to be a legitimate NFL starter.
