It doesn't matter what he could have done without surgery. If you want to delude yourself into thinking that without surgery he wouldn't have been a one-slam wonder, go ahead. Whatever helps you sleep at night.
What matters is what he is capable of doing now. And he has been full of fail for years. The idea that he will magically 'come good' at some unspecified time in the future is just fantasy-land stuff for his fans. That you think he is still recovering from his surgery three years later is proof enough of your gullibility.
Del Potro is a nice guy and he deserves fans that appreciate him for what he is - a solid top 10 guy. Not mindless tards who are only on his bandwagon because they think he is a slam contender. One day you will accept that this is all that Spudtro is capable of - picking up the scraps of 250 and 500 tournaments left behind by better players, maybe one day jagging a MS1000 if he's lucky.
In the meantime, would you like to buy a bridge?
You can repeat the same BS over and over, it still won't make it through. Although I have to give it to you, the idea that Del Potro deserves fans who don't believe in his potential is, well, quite original to say the least, far from your trademark hater stuff.
Ironically, your attempt to denigrate Juan ended up as a bigger compliment than even his biggest tard could ever be capable of. By implying that winning an Olympic medal and making QF/SF of big events among other things less than two years after underdoing major surgery is 'full of fail', you're the one overrating Del Potro and his talent to unwarranted extents. You accuse his fans of overrating him, but you did more of that in one sentence than any of them ever did here on MTF
That you think getting his wrist back to full health is enough to instantly starting to play at the same level he was before shows either extreme hatred/bias or extreme lack of knowledge, for your own good hopefully the first.
