Don't forget fricking Krygios was playing in the final of a Masters event. LolZverev didn't even make a Slam QF and ended the year #4. Dimitrov made one Slam SF and crashed out early in the other 3 Slams and did nothing in all other big tournaments except Cincy and WTF but ended the year #3. The USO was a wasteland where Nadal didn't play anyone in the top 25 but sure 2017 was stronger. Lol.
