It's not just that, it's just another overwhelming statistic showing this
he's defense is about technique and intelligence, adjustments, he's the best of all time
people say zab gave him problems when had zab's jab completely neutralized in the second round
even fights were it might look rough like maidana when you break it down, maidana only landed 20 percent of his punches, having your opponent only land 30 percent is very damn good, 20 percent is insane and that's what he averages across the board, it's insane
So it's the stat itself it seems?
Now, I believe Floyd is Top 5 DOA in defense as well, but statistics wise, he's not the best today....it's Guillermo Rigondeaux who allows a 16% connect rate on him for his career while Floyd allows an 18% connect rate for his career (as recent as 12/2013 via compubox

Defense takes into account not allowing your opponent to hit you, but also your competition (which Floyd has faced great comp) and the punches you can sustain (considering Floyd has never been officially knocked down in his career, I would give him the edge over mostly everyone because his chin is strong and a body shot hasnt taken him down either)
I am
on this though, because it's a slippery slope. Going by opponents connection pct to use as a basis for calling someone the greatest, you'd also have to go by total connect pct landed on opponents...which means the top 9 best offensive boxers today are in order Floyd, JCC Jr, Alvarez, Ward, LSC, Khan, Agbeko, Lara, and Lamont Peterson and the most COMPLETE boxers today (+/- on punches landed for them vs landed on them) are Floyd, LSC, Lara, Ward, Canelo, Rigo, Wlad, and Moreno. I dont think anyone would stand behind that statement, but it cant be 1 way without the other
