As Rams coach Jeff Fisher observed at the Scouting Combine, every player who has surgery has a successful surgery, and his rehab is always ahead of schedule.

We’ve found an exception to the rule.

Patriots tight end Rob Gronkowski reportedly isn’t ahead of schedule after tearing an ACL late in the 2013 regular season. According to Albert Breer of NFL Media, Gronkowski is merely on schedule.

Per Breer, Gronkowski is “right where he should be,” and he soon will start jogging.

Of course, with Gronkowski “right where he should be” could yield to a reality of protracted delays and reports of coaching-staff and/or teammate frustration. But it’s hard to blame Gronkowski for waiting until he’s truly 100 percent. In recent years, he’s become the NFL’s version of Cavity Sam, with ankle surgery, back surgery, and multiple forearm surgeries to go with a major knee surgery.
