I see they both have 15 pro majors, which is the most respectably in that category. I don't know how to separate these two. Rosewall has 8 slams to Gonzales' 2 in addition to the pro majors, so technically Rosewall has more and would lead him to a higher tier. However, from what I've read Gonzales tends to be rated higher by experts. Is that cause he has more time spent as number 1?
