Shamrock is a downgrade on Jason Thompson. Kimbo needs much better opponents to actually test tis guy. He needs a Frank Mir or someone along those lines. Shamrock has lost every match for loke the last 3 or 4 years(5 in a row?) and has been beaten by some questionable talent during that time. Shamrock needs to retire. Kimbo needs better opponents, but his training under Bas Rutten to the test.
Lesnar and Couture should be a good bout.
Lesnar has a huge size advantage(so did Silva though)
Lesnar is arguable the better wrestler.
Couture, without a doubt is the much smarter, craftier and all around better talent once the fight hits the ground. If Lesnars ground game is the same as it was agains Mir and Crazy Horse, Randy will rip him apart.
