Though all of this is pointless for two reasons:
1. Jones said he turned down the fight due to lack of preparation, not the legitimacy of Sonnen. So, no, you don't get to substitute Jones' explanation with one you prefer.
2. Jones got his title shot with no legitimate top-10 wins. Period. He was a phenom even then and we all saw it. But he didn't earn it. He got it because no one else stepped up and DW saw something in him. The LEAST he could do is humor DW when the same situation arises while Jones is the title holder.
