I first thought "This HAS to be fixed" but then I thought:

1. The key to a proper fix is making it look real
2. Why did Green want to fight Briggs so badly when Briggs had been happily retired?
3. Why wouldn't you expect an active boxer to destroy a retired boxer when if these two were in the same ring in their primes you'd still expect Green to KO or stop Briggs?

It doesn't add up
