UFC 109 Betting Odds and Main Fight Card

So UFC 109 is now officially under 2 weeks away! This is a great time to start getting your bets in online/put in fantasy UFC votes! I posted my fantasy selection a few posts ago, be sure to check them out! So here are the official betting odds for the main card of UFC 109:
Randy Couture (-400) vs Mark Coleman (+300)
Nate Marquardt (-350) vs Chael Sonnen (+250)
Demian Maia (-375) vs Dan Miller (+275)
Matt Serra (-135) vs Frank Trigg (+105)
Also, this is old news, but in case you didn't know Josh Koscheck was originally supposed to fight Paulo Thiago (both fighters were on the main card of UFC 106) but he had to drop out due to an injury that is still unknown. However, the fight card will not suffer anymore because Mike Swick has replaced Koscheck to face Thiago. This fight card is not the greatest the UFC has seen, but it will definitely be entertaining, especially watching two legends during the main event. Don't miss it!
