UFC 145 - Looking For Upsets

You may have heard that Jon Jones will defend his light heavyweight title at UFC 145 against former training partner Rashad Evans, or you might have been living in a cave.  Anyway, it just so happens that this is just the headlining fight of a really interesting card.  It seems like the UFC has decided that since the main event is a sure fire pay-per-view seller, they can fill up the under card with lesser known fighters.  Well that's just fine because as unknown as some of the fighters may be, some intriguing fights are in the offing.  On paper, it seems like a night of fights with pretty clear favourites, so let's have a look where the possible upsets lie.
