Sherk remains a one dimensional fighter, and therefore highly predictable.
He just doesn't have the reach to become a top level striker, and his short limbs place him at a disadvantage when trying to sink in submissions.
That leaves his wrestling; unfortunately his takedowns are fairly predictable. The faster LW's are going to avoid them easily.
His strength, determination and cardio make him a formidable foe, but his lopsided loss to frankie leads me to believe that his days of contending have now passed.
Sean has had a tough time picking up W's since he tested positive a while ago.
I'd love to hear thoughts on how he's going to reinvent himself, but I don't see it happening, quite frankly.
