Its been a while since I've seen Liddell on the ground fighting with is past matches all been won from standing. Those wanting to stand with him might find it a difficult approach especially with how easily Liddell can knock someone out.
Now if Liddell was to fight someone and be taken to the ground, it would be interesting to see if he's rusty and the shape of a fight can esily change when fighters are in that position.
If Liddell was to fight on the ground in his next fight and win in good fashion, It would be hard to ignore the fact it might just be the best in the business. As yet, I'm not rating anyone to be the best especially Shogun who in my opinion has yet to prove me!
