Mohegan is between Hartford and Providence, so there are two metro areas that meet there. XL Center is mainly just Hartford and maybe Springfield.

Also, for the same reason the CT Sun plays at Mohegan- more people are likely to buy tickets if they're there to gamble and happen to notice an event they're interested in, or vice versa where the fans are more likely to come if they can do other fun stuff like gamble.
