I think that actually makes sense because it's close to what you say at the end. Maybe not "pro-quality 95+" but at least a 2nd that has some pace along with kick/shape to it and doesn't get you murdered against a solid player.I just noticed something funny on the descriptive UTR chart. A "consistent first serve" is an earlier / lower-level achievement than "a consistent second serve"?
Maybe they mean "pro-quality 95+ mph second serve" or something. But I don't see how you get beyond beginner tennis without a consistent second serve.
As for progression, that's what I have seen a lot at the 3.5 level -- dude hits his 1st hard and flat getting it in maybe 60% of the time. Then for his 2nd he pops it in to avoid the DF. Sadly, I actually hate these fluffy 2nd's as I still struggle to generate my own pace. Of course, thankfully most guys don't figure this out and keep firing 1st's that I can do something with.
Just like BG says in Winning Ugly, it's all about figuring out "who is doing what to who[m]" -- so many smart people play dumb tennis...
