I don’t need down comforters to keep me warm this winter. I don’t need Granny’s quilts or my father-in-law’s electric blankets, either. All I really need are a few emerald sheets — uncut, of course — from the upcoming 2012 Prizm Football. That’s what I immersed myself in yesterday afternoon that ultimately heated up most of the Panini America Production department.

Cue the trumpets: Green Prizms aren’t just for basketball anymore. Green’s good for the gridiron, too. Indeed, those retail-exclusive Green Prizm parallels that have ignited a secondary-market feeding frenzy in 2012-13 Prizm Basketball are coming to 2012 Prizm Football — and once again, they’ll be available only in retail.
