I don't agree. The only thing Kobe really has trouble on defense is fighting through picks. He was never good doing that probably because he didn't want to waste the energy. Later ie 2010+ on he stopped caring about closing out on 3 shooters which would also get him trouble.
But defenders blowing by him on the perimeter in his prime? Nah.
