Dean Spanos has spent the past eight years and millions of dollars trying to find the right deal to keep the Chargers in San Diego. The downtown site near Petco Park that?s being considered could be the last one before something drastic happens. But Spanos doesn?t suspect Sunday?s loss or the lack of a Super Bowl title will affect the outcome. ?I think we?re moving toward the end,? he said. ?We?re in the early stages of the downtown process and it remains to be seen whether it plays out. We?re supposed to get a financing plan soon. The mayor (Jerry Sanders) says he?d like it to be voted on in 2012.?
