The Jets fear that quarterback Mark Sanchez won't be ready for their offseason practices, ESPN.com is reporting. Len Pasquarelli writes, "Some team officials fear that Sanchez, who has not yet begun to run, probably will miss most, if not all, of the Jets' offseason program while he recovers." Sanchez had surgery Feb. 17 to strengthen a patella tendon injury he suffered in college and re-aggravated last season.
