This kind of behavior shows lack of confidence imo. If you're confident, you'll go out there and hurt ppl until you get the shot. If not, you'll start bashing the champ saying he's a coward because you might not get the shot anymore.
Or maybe Hendricks understands that on any given night anyone can lose and once you've earned your shot like he has, every fight in between now and the title shot is a chance to get upset (like he did to Fitch) and lose your place.
Hendricks should just pull a Condit and sit out for a year until he gets his shot. Now that would be brave. /sarcasm.
