Doesn't HSG also own the Crew? Look at that difference, the started out with a stadium they knew was temporary (like the cotton bowl) then were lucky enough to find funding and build their own soccer stadium in about 2 years. And it wasn't too far from the area they wanted.
And since the Burn was "league-owned" for 8 long years(in other words, it's just there taking up space in the league) they weren't too fast to find that new home. So intead they went through the trouble of building a fan base in one place. Now HSG's first business decision right off the bat is to get the hell out of the cotton bowl right away and get a new stadium deal (in other words, repeat the Columbus Crew plan here). But now that his new stadium is in a far off town, there is no need to even care about how well the team does or firing coaches. There's also absolutely no need to even care about the old cotton bowl fan base whatsoever... why bother, it's a new town, a new fresh start in a brand new market. THAT's when he'll care about new coaches, new players, ect.
