It's broad. Lopez and Karlovic are close to 40 or 40 and still they are dangerous. This was unheard of 20 years ago, that players who were never among the very best would still pose a threat at that age. Ditto Isner, Ferrer (until recently), Verdasco and many more.Yes, I generally agree. There's definitely been an age shift. But, I think it's been magnified by the Big 3, meaning that while there's definitely a shift generally, they shift for the Big 3 is even bigger. To put it another way - I expect more players because of GAS to have their best Slam performances or win Slams later than in previous eras. But, I don't expect players generally to follow the Big 3 and still be winning Slams or having their best performances in their mid 30s. So, the average player now peaks later than previous eras, but I don't expect them to keep that up as long as the Big 3. GAS isn't universal at one level - I still think they'll still be plenty of players who "age out" around 30 (which is later than it used to be) and if they keep on playing won't ever get back to their peak level.
Did this make any sense, lol. The shift is real, but on average not as broad of a shift as it is for the Big 3.
