Interesting - sounds like a lot of you base p4p rankings on how each man would perform at a certain weight. But that's difficult! I mean, if PBF were a heavyweight - 220 or so - do you think he'd still have the same handspeed and reflexes? So it's difficult to compare a lightweight fighter against a heavyweight fighter just on the argument "how would they fare against one another at the same weight". So many of the attributes that define certain fighters would not hold up under the "transformation" to a different weight.

Sounds like a flawed way to judge p4p, but, my opinion isn't much

That's why I look at skill, heart, and COMPETITION! These things are completely independent of weight.
