Which is tantamount to saying that a player's game and his results are completely unrelated. If we accept your premise on Blake's Forehand - that its so much better than so many others - then what good is having such a shot if it never does the job for you in the tournaments that matter most? It matters not one whit that Blake can hit a great Forehand when it's 1-all 15-all. The question is, where is that same shot when it's 4-all 30-all? Deuce? Break Point down? Set point down? Or more to the point, where was it at the business end of Majors in the 2nd week? If such a shot isn't there for you in the moments that matter most, then the shot itself doesn't matter all that much; having it is essentially useless. Where do you think Nadal's career results have come from? They've come from the same shot - his Forehand. But Nadal, unlike Blake, can pull off that shot optimally when it mattered most - whereas Blake always found a way to choke that shot when it counted.
I think there is are some key points you are not considering with this argument. For one thing, while Blake has a great forehand and foot speed, as well as a solid return of serve, those are really his only notable attributes that set him apart as a player. His backhand was "okay", and volley was "okay", and his serve was "okay", but at the end of the day he lived and died with his forehand. The main differences between Blake prime (06-07) and Nadal prime (05-10) were largely A) mentality and approach to the game, and B) endurance. Nadal played every point (regardless of the score) the same, didn't often succumb to the pressure of the situation, and played with more margin (within himself) going for higher percentage shots. Blake on the other hand would often succumb to pressure, play "high risk" tennis, and go for low percentage shots when the pressure was on. That has nothing to do with forehand technique, that has to do with mental composure. Also, endurance is one of the hallmarks of Nadal's game and notably one of James Blakes great weaknesses (a simple comparrison of their 5-set records demonstrates this). That's not a "forehand" issue, that's a conditioning issue. So there are a lot of things that factor into results, which is why I tend not to give too much strenght to the importance of one shot.
The comparison to Blake & Roddick is ludicrous. Roddick won his lone Major (and reached the Final of 4 others) because of his Serve, not his Forehand. More succinctly put, the Roddick Serve was far better than the Blake Forehand.
Again, for reasons just given above, that is simply NOT the case. Roddick won his one-slam because he played overall BETTER than the opponents he faced in that match (namely, not Federer), and where he only had to face ONE single time grand slam champion (Juan Carlos Ferrero) in rout to his victory. But listen to any commentators of his matches from 03-04, and his forehand was listed as one of the best in the game (at the time). He was actually a two-trick pony then, rather than the one-trick pony he later became.
And it's more than rich irony that you embed this particular video to showcase Blake's Forehand. No matter how beautiful it looks here, Blake lost this match - to the very guy you say he caused problems (and incidentally, after early wins against Nadal, Blake didn't beat Nadal again starting with the match before this one, 2008 Indian Wells). The video clip proves the entire point I'm making. Thanks for that
.
Actually, the video clip includes two of his three victories over Nadal, and one 3-set loss. And it "proves" nothing other than what an awesome forehand technique he has and how many other players would trade their forehand for his any day. You're entitled to make non-relevant factors such as head to head record part of your argument for great shots, but I choose not to. Again, different strokes for difference folks!
