SUNRISE, Fla. -- Joe Riggs has always been one to tell it like it is, and when MMA Fighting spoke to the 170-pound contender on Wednesday, he was no different. Riggs talked about being frustrated over the fact that his fight against Jay Hieron was relegated to the Strikeforce: Miami undercard, while unproven fighters like Herschel Walker and Bobby Lashley were pushed more. The 27-year-old also discussed his place in the Strikeforce 170-pound division and why he still doesn't consider Kimbo Slice a legit mixed martial artist.
