Weaknesses of shoulder roll.

[Sleepwalker]

I never really study shoulder roll, but facts are

1. Leonard showed the way
2. Oscar, Miadana and Castilio were quite effective
3. This is serious: Floyd faced many punchers, people with good one or two signature punches, but he never really faced a real flurry puncher who had the technique & power of Tyson or SRR or SRL, I mean this:

Oscar / Castilio had the technique, but lacked power
Maidana 1 had the power, but technique wise he was sloppy

I was amazed at how grungy Maidana was yet he was still able to keep the fight close.

I'm sure this had to drive ATGs like JCC and Duran nuts if they were watching
