Not everything, and "to a degree" can be to a minor degree.
Obviously, Cannoniere was able to continue the fight, and was able to throw strikes and kicks, so "everything else" and the "degree" is not demonstrated. Everyone has pointed out Franklin throwing punches with a broken arm, and being able to finish Liddel via KO, while fighting with a broken arm. Pettis continued to fight and won with dislocated shoulder, which would be much more debilitating to overall ability to perform than a fractured forearm bone.
If you were making the argument "everyone is lauding Whittaker, but he beat a one arm fighter" that would be one thing, but you are specifically talking about Whittaker's jab, where the ability to defend an opponent trying to land that jab has almost nothing to do with that arm.
No need to offer any "if... then" about whether you are an ignoramus. It was a stupid concept, that you refuse to let go of.
