it's not a matter of letting it go there, Chael Sonnen is the best wrestler in the MW division, if he wants it on the ground it's going there whether Anderson Silva likes it or not, if Anderson wins I see it coming by way of catching Chael with a flying knee whilst he shoots in for a takedown, Chael would be wise to take the fight to the clinch and get takedowns from there, instead of shooting on him and risking diving face first into one of those knees.
