Faceoff swap out?

Question

Probably the only question in hockey that I've never been able to answer.

Why do referees occasionaly make a winger or somebody other than the usual center take a faceoff?

Answer 1

I think if the center trys to swat the puck before he drops the puck..like if he's being much to agressive then he'll switch it.

Answer 2

Rule 76.3 Procedure

As soon as the line change procedure has been

completed by the Referee and he lowers his hand to indicate no

further changes, the Linesman conducting the face-off shall blow his

whistle. This will signal to both teams that they have no more than five

(5) seconds to line up for the ensuing face-off. At the end of the five

(5) seconds (or sooner if both centers are ready), the Linesman will

conduct a proper face-off. If, however:

(i) One or both centers are not positioned for the face-off,

(ii) One or both centers refrain from placing their stick on the ice,

(iii) Any player has encroached into the face-off circle,

(iv) Any player makes physical contact with an opponent, or

(v) Any player is in an off-side position,

the Linesman shall have the offending center(s) replaced immediately

prior to dropping the puck.
