Thanx to both El Gamo and pareng pacstrightleft (cc right back).
Yup, I think Don still needs to be tested more to be considered a real great champion. Two more good fights are I think enough to prove if he is for real or not. So I hope those fights are coming soon, including possible Sakata and Mijares fights (I haven't seen either of the two but I'll take your words for it).
