Weatherford likes Sanchez. He wants him to succeed, despite playing for the Jets' cross-stadium rivals. He just hasn't seen the development he'd have liked to by now.
"I like Mark, I think he's a very talented quarterback, but from my standpoint, I haven't seen a lot of maturation from the position," Weatherford said on NFL.com's "Cover Two" podcast Thursday. "When you're a quarterback and you come in, and you're expected to be the face of the franchise, and you're expected to lead the team, that's a lot to take on as a rookie, but as the years go on, I think you're expected to mature, skill-wise, and also mature as a leader, and to be honest with you, as much as I like the guy, I just haven't seen that."
Sanchez was promising as a rookie quarterback, but he hasn't developed much since.
