I sense that there is a lot of potential in the realm or world of sporting -- however the new extension market may have a lot of trouble with liquidation. You have these domains targeting a certain niche -- in this event, a certain sports team. .online and .mobi sales in general have been less than liquid as compared to preferred TLDs.
With these certain acquisitions, I can see a low to high XX sale marketed towards a fan of the team.
All the best!
