JIM REEVES SAN ANTONIO — There’s an outside chance someone will mistake the upcoming message as downright blasphemy, or at the very least a blatant case of Glory Days Syndrome.That’s understandable. There have been brief intervals over the last few years where yours truly has indeed succumbed to the feverish hallucinations and fantasies that strike old fogies from time to time, so a relapse, I suppose, is entirely possible, if not downright expected.But it occurs to ol’ Jim Bob here, peering through the sleet-filled, air-conditioned ether of the Alamodome as the Dallas Cowboys began training camp this past week, that there’s at least a passing similarity offensively to some teams that once graced the almighty Star at Texas Stadium.I’m talking, of course, about those ’90s Cowboys teams that ultimately provided owner Jerry Jones with three glittering pieces of priceless hardware for his Valley Ranch office.Granted, this venture requires more than just a bit of squinting and some forays into the depths of the imagination, but I find myself doing a lot of both these days.
