These dudes are legit. One of them, Colin Baxter, was the executive producer of Sonicsgate; a documentary detailing the absolute shady dealings that went on between David Stern and Clay Bennett to uproot the Sonics from Seattle and ship them to Oklahoma City. Stern's panties were leftover wet from OKC's foster home care they gave to the New Orleans Hornets immediately following Hurricane Katrina's ass-kicking.
Well, Colin Baxter and his buddies weren't too thrilled about losing their team after 41 years of loyalty from the Pacific Northwest city. So they did what any other die-hard fans would do: spend $4000 a seat, plus airfare and hotel, to be present directly behind the Oklahoma City Thunder's bench during game 4 of the NBA finals.
Die-hard indeed, literally. The walking dead Seattle fans are sending a message, artfully tactical at that.
