I see some coaches with a bunch of teams - coach_dk comes to mind, as does jenningss - that share a common region (in both examples, the Pacific NW), and I've always just assumed that these guys live or are originally from the Pacific NW. Likewise, I've always assumed that if I see a coach whose cross-world resume has him at Bentley, Post, UConn, Brandeis, and SCSU, he's from that part of the country.
But does anyone do this that doesn't have a RL connection to the region? Are there any longtime Texans out there with HD gigs at FSU, Miami, and half of the Sunshine State Conference? Or Chicagoans that now coach at San Diego State just because they liked how recruiting went for them at UCSC and Loyola Marymount?
