I was sure Cash Sirois was behind RetroMavs.com. But, no: He sends word that Ken Bonzon and Steve Chavera, the webmasters for Your Dallas Mavericks, are behind the champs' new flashback site, which made its bow yesterday and, so far, features a few video flashbacks (including Popeye Jones and Tony Dumas reviewing Dumb & Dumber, and poor Cherokee Parks) and other random items about to get less random. Now I know where to wear this game-worn Alex English jersey.
