The maligned quarterback told WEPN-AM in his weekly appearance Tuesday that New York's postseason hopes will end if he continues to complete less than 50 percent of his passes, as he did Sunday, and the Jets "lose the turnover battle, lose time of possession, all those stats."
Sanchez threw a career-high four touchdown passes, but acknowledged he didn't think he played a good game.
"I feel good, physically and mentally," he said. "I'm just so focused [because] I want this to go right, because I don't want to miss an opportunity like this, with this kind of talent and this kind of coaching.
"I'm usually -- 'bubbly' is not the word, but I smile a lot more. We're short on time here, and there's no time to mess around or smile or even laugh, in my opinion."
Safety Jim Leonhard criticized fans during his weekly spot on WFAN-AM earlier Tuesday for booing Sanchez before the game, saying he was "frustrated" by the jeers.
"I think we have a great crowd," Leonhard said, according to the New York Daily News. "I think probably for one of the first times I was kind of disappointed. Our starting quarterback gets booed in introductions. As players, you kind of turn to each other and say, 'You know what? I guess weâre in this one today by ourselves.'"
