You don't want to go down that road! After watching the sport since '73, there have been plenty of instances where each great player had periods with little to no resistance! OTTH we all know eras where players like Martina, Chris, Steffi, Serena, Roger, Bjorn, McEnroe, & Nole owned a season or 3! A lot of it was they were superior, actually toying with their competition, but then the other side of the coin has them coasting with tour fairly weal and lackluster! For Martina, '83 & '84 were as great as any in the history of the game! Besides winning 6 majors in a row, she barely lost sets; serving up bagels and chopsticks! It was embarrassing for a while! Steffi had periods of just being at the top of her game, but then her coin has 3 sides; add the mediocrity of the WTA for a while plus Monica's stabbing changing tennis history! This era has had a little bit of both; great play and apathetic results from the tour! First Roger owned it from '04-07, intermittent greatness of Nadal in '08 & '13, with the rest going to Nole until now! Murray's trying to make an impression, but it would be short-lived and we all know it! The question is, who's the next great player and will Nole add a few more majors and Masters events to his record before totally giving it all up?
