As mentioned before, he may be just a kid... but so many kids were way ahead of him at his age and development. Going against the hardest hitter in tennis is quite a challenge but seeing him in interviews didn't impress me in the least. He was more star struck and interested in the attention he was getting ("look I'm going to be a marketable figure on TV and popular with my friends"). He's 17 but still as mentioned, just like Chang, Aggasi, Courier, Sampras were once......... They have raised my expections on the quality of tennis and preparation for young men going pro.
For someone who is just new to Tennis maybe Jenkins would be an interesting figure, but for me....... I'll go back to watching Federer, Srichaphan, Roddick, Agassi and the likes.
