It is an interesting situation. I'm no business expert, but it seems to me that if Best Buy bought it they should just completely do away with the Radio Shack (or The Shack) brand. Nobody trusts it. The word "outdated" immediately comes to mind. I think their focus on phones could work, but under a different name. Call it "Best Buy Mobile" or something. I'm not a big fan of Best Buy, but they have been doing well lately and I think people trust the Best Buy name.
As for the team, they're lucky they have Lance. Like him or not, sponsors want him. I'm sure the team will continue on as normal. I think a Best Buy kit could look pretty nice if they design it correctly.
