I agree that he is not a finished product, but man you guys are overrating Chandler. He is a very solid fighter but he wouldn't be a top 5 UFC LW let alone champ right now.
His whole career thus far is based off a good performance over Alverez...another highly overrated fighter. Chandler started gassing half way through that fight...that won't fly vs. the Pettis', Bendo's, and Diaz's of the UFC. Chandler is well-rounded but does nothing real well.
Alverez would get dropped and finished in the UFC. Chandler would lose decisions in my opinion.
As for Gil, I'm not sure. Everyone wants to jump off he wagon because many feel Thompson won that last fight. I don't think he would beat the champ right now either. But would't mind him getting a shot.
