Shawn of 'Psych' is apparently a displaced Chargers fan up in Santa Barbara. The placement of such a distinctive sweater / logo makes me wonder if the Chargers paid for this. There's a couple of scenes where he wears it. Anyway, here's a video as well: http://coolspotters.com/clothing/san-diego-chargers-sweatshirt/and/tv-shows/psych/media/389321#medium-389321
