First, calm down. Second, I watch a lot of tennis. I also play -- a lot. Third, 1st serve percentage or points won means nothing if you aren't getting results. That is an extremely misleading statistic... not unlike break points saved.
You said "Federer's problem is that whether he's serving or receiving...
he always starts out having to play defense because his first shot is mediocre." I replied because it is patently wrong and anyone who knows anything about tennis would laugh at reading such muppetry. He may not be as good as he used to be but he's certainly not "always starting out playing defence" by any stretch of the imagination.
His first serve is absolutely nowhere near where it used to be. In my opinion, the two shots that have declined (which is what this thread is about) is his serve and his return game. IMHO, the serve and return have declined because of his aching back.
The is true but makes no difference to your absurd comment about him "
always starting our having to play defence." Sure he's nowhere near the force he once way - but that is not what was wrong with your claim.
You comparing Federer to Isner/Raonic/Isner says everything that needs to be said.
Yep, it says that moreso than practically every player on tour other than a few exceptions he IS NOT "always starting out having to play defence."
You obviously have no clue about strength training as a primary tool for injury prevention.
I do.
If you remotely understood my post...
I did.
you would infer that I think he should have strength and fitness training to offset his obvious back issues.
His back issues may be for congenital or other reasons which no amount or type of strength training could have any positive effect on. Or do you know exactly what his issue is?
I can answer that for you. No, you do not.
His issue may be helped with strength training. Regardless, you asserted "if Federer would stop being so stubborn and commit himself to some serious strength and fitness training.."
Show me one piece of evidence you have that he does not do serious strength training or is too stubborn to? (don't say he's skinny because that'd by showing muppetry of the highest order) Perhaps he does and it's not what actually he needs to improve his results.
I supposed when Lendl got near the end of his career and was having back issues what he really needed to do was more strength training? Nope.
And Nadal - should he be doing more strength work on his knees? Probably not.
Go read "Open". Agassi always had Reyes, but he personally attributed his comeback to his recommitment to strength and fitness training at a level he never achieved before. He did this in his book.
And? How can you possibly compare their situations? We know jack all about Federer's specific back issue. Maybe he has a sacralized vertibrae (commonly 5L) - a relatively common issue which more people don't realise they have because they don't put it under enough stress to aggravate it - and one which most strength training efforts make worse.
