EAST RUTHERFORD, N.J. – Football coaches love to replicate game conditions in practice, even atmospheric ones. And Pete Carroll buys in – to a point. The weather outside is frosty if not frightful, and will be for Super Bowl XLVIII on Sunday. But Carroll’s Seattle Seahawks have been practicing indoors at the New York Giants’ facility, which would seem to give the edge in acclimatization to the Denver Broncos, who are going outdoors at the New York Jets’ field in Florham Park.
