Kickers, by and large, are susceptible to jammed eyelids and other mental maladies, and can get into a funk PDQ. Crosby went through such a period just a couple or so years back, as I recall.
Last year, he didn't stand much of a chance. Poor snaps and holds are bad enough, but piling on consistent protection breakdowns is more than enough to give anybody the yips.
However, I don't think Crosby had one, and his mechanics were good, so I think if those issues are solved, he will be fine.
