The problem with Williams moving up is if he can't punch at WW, he may have even less power at 154 especially because he arm punches and doesn't use is weight properly. If he punched correctly, the power would follow him up in weight, but since he slaps, power won't carry. He's a guy who relies so much on workrate and size advantage.

One the other hand, 154 is more open, less talent overall. It would be interesting to see in him with Vernon Forrest.
