His kicking lets him down so I assume that's why he doesn't make it into the top 20. His kicking was only 68 or 70 on the last game so that will affect his overall somewhat.
Buffon can never be rated too highly.
Howard gets a nice improvement which is deserved.
I mostly agree with the list to be honest. But again, it's just a list of highest overall ratings, which are a combination of many things.
