Interesting comment, though I think Wilander is just being humble in deference to his idol and fellow Swede. I remember how Mats swept through Lendl, Clerc, Gerulitas, and Vilas to win the French that year. He was so unbelievably consistent it is hard for me to imagine anyone, including a rapidly burning out Borg, beating him. Granted Borg's probably the GOAT on clay but at that time in their respective careers, I believe Wilander just had too much convinction to his game and that the torch would have been passed sooner than later even if Borg continued playing
I don't think it was Mats being humble, its like if Fed skips Wimbledon this year & Murray wins it, then says he would have no chance had Fed played. The gap between Wilander & Borg was huge in '81/'82/'83. Borg would have been the 4 time defending champion had he played in '82! I don't see how an unseeded player who just played a defensive style could have troubled him.
And Mats didn't win the French easily in '82, it was a battle the whole way(while Borg swept through most of his Frenches, completely destroying the same guys that gave Wilander so much trouble in '82)
Here was Mats' route to the title in '82:
R128 Cortes, Alejandro (COL) 6-4 6-3 6-4
R64 Motta, Cassio (BRA) 6-3 6-4 4-6 6-2
R32 Luna, Fernando (ESP) 6-3 6-1 6-0
R16 Lendl, Ivan (USA) 4-6 7-5 3-6 6-4 6-2(Borg won in 5 over Lendl the year before, but it was a lopsided 5 setter, the sets Borg won were 61,62,61)
Q Gerulaitis, Vitas (USA) 6-3 6-3 4-6 6-4(Borg always destroyed Vitas on clay, no way could he ever get that many games off him)
S Clerc, Jose-Luis (ARG) 7-5 6-2 1-6 7-5(Borg even beat Clerc easily in Monte Carlo in '83-with a wood racquet-while he trying to decide whether to comeback fulltime)
W Vilas, Guillermo (ARG) 1-6 7-6 6-0 6-4(this match was close to 5 hours. Every time Borg played Vilas at the French-or pretty much anywhere-he destroyed him, so if Mats had so much trouble with Vilas in '82, how could have possibly beaten Borg? And the fact that Vilas even made the final that year showed that Borg probably would have had no trouble winning it that year, Vilas was on the decline in '81, I think Borg's retirement inspired him to that resurgence in '82. Probably the same with Connors winning Wimbledon in '82. Shows just how good Borg was, his contempories immediately saw a boost in their results when he left the tour)
Also keep in mind, Wilander lost to Yannick Noah, arguably the weakest slam champion of the Open Era, in '83 as defending champion. Could you really imagine Borg losing to Noah at the French in his prime?
Wilander is a great player. But like Rabbit said, he played a lot like Vilas, & Borg had no problem with that style. Plus Wilander never really dominated the tour, even on clay, so not sure if the comparison to Borg is really valid.
Borg could have been a threat to win the French for a number of years had he not retired(and really the game didn't get that powerful when they first switched to graphite, I've seen those Wilander-Lendl matches on clay & Borg-Vilas were hitting harder with wood. Wilander & Lendl basically traded moonballs most of the time when they played each other on clay, while Borg was more aggressive. Had Borg stayed & used graphite, his topspin would have been even more dominant with graphite, since he was one of the few guys who could generate heavy topspin with wood, graphite would have helped his volleys as well. Borg had a lot of mishits with wood, graphite could have made him better, like it did Mac)
But Borg really didn't care about the French, he cared about Wimbledon, & he (incorrectly) assumed Mac would dominate there after '81. After Connors won Wimbledon in '82, I'm sure Borg kicked himself for his sabbatical.
