I used to be a huge fan of mid-MLS season US tours. Now because of international duty and general injuries, they are almost a pain. I have easily forked over big bucks to see other Premier League clubs play in the past. Now I just want my local team to have a couple of healthy CB's before August is out. And I know a lot of other American fans who feel that way. Obviously money is a the huge factor, but I don't think these games really do anything for the MLS otherwise. For the stateside PL supporter (who doesn't follow the MLS) they are obviously huge though.
