Turbo retired because he was 403 years old. Only so many years you can do double flip dunks off a trampoline 20 feet in the air.
I know it pissed me off for the rest of the game for sure but I pretty much told the guy where he and his suggestions can go, funny thing is that I usually sit on the aisles so that if i get up and cheer i move into the aisle so the person behind isn't getting blocked but some people just want to be asses
I recently heard Clutch's wife being interviewed on the radio. She and Clutch know Turbo. She said the wear and tear on Turbo's body doing the stunts forced him to quit. I also liked Turbo better than Clutch.
