Are you sure? I think it might make the difference between him having 3 rounds of stamina or 2 rounds.
I witnessed Briggs back Sergei Liakhovich up against the ropes in the first round of their fight and saw him unload such a heavy arsenal of punches that it had Liakhovich scared shitless and he fought a very boring and complacent fight from that point on. Briggs is every bit as powerful as he looks. You wouldn't want to be standing in the ring across from that man taking his bombs.
Briggs best hope is to sprinkle his dreadlocks with shards of broken glass & use his head, like Lewis did.
