You have 6 more years if you fight until you're 35. You have 3 TKO wins. If you fight every 4 months, you'll retire 30-0, 21 TKO's, with GSP's belt.
You will be exciting. Fans will cheer: As-Kren! As-Kren! As-Kren!
You will never need to throw another punch again ever. Get the takedown, elbows to the body/limbs. Grind up against the fence, elbows to the body/limbs. Knees to the body/limbs if you want to get a little risky. Why no elbows to the head? Avoid broken elbow dummy.
