Jimmy Connors’s longevity is underrated.

Won 2 slams in his 30s.

Made 3 Slam finals in his 30s

Made it to at least the semifinals of slams 11 times in his 30s

Had that big run to the US Open semifinals when he was approaching 39 years of age.

Finished as the top 3 player in the league from the ages 30-32.

Finished as a top 5 player on the league from the ages 30-33 and at 35.

Consistently made the semifinals or finals of non slam tournaments until he was like 35. He also won a handful of those tournaments.

He definitely doesn’t have the longevity of the Big 3 but his longevity during his time was good.
