i dont know, but i think he took some face offs last year on the power play. how was he as a center (if he did play center) and if he did, wouldnt it be easier to have him at center and look for a winger at the trade deadline?
I noticed that last year Prucha looked very strong on the few faceoffs he took. This year, he hasn't taken as many, so I can't pass judgement. The main issue with him playing center is his small size, which is why it'd be best (most likely) to keep him on the wing.
I think the point is moot because to this point, Renney has not shown enough faith to keep him on the 2nd line as a winger. Knowing the responsibility that goes along with being a center, both offensively and defensively, it is asking a whole heck of a lot from Prucha...
