I'm not defending Wade here, Im defending cheap shots that aren't probable injury risks.
Maybe it's my own sports experience, but as players get more experienced, they learn some tricks of the trade to inflict minor nagging amounts of pain. Wade's leg kick should've been a flagrant, and deserves a 1 game suspension, but that's where it ends for me. It's not much different than a hard jab to the small o the back/kidneys, or a hard pinch and twist to the body, an elbow to the ribs.
I see Bruce Bowen's trademark leg kick under the legs as a far more egregious offense. Bruised pride and balls are a far lesser price to pay than a broken ankle, or high sprain.
