i think it deserves a thread of its own, since both are by far the best next generation stars. Nick under-performed to start the year, but make no mistake he is a prodigious talent and is arguably more awesome on his day. After scoring wins against the big 3 when they met the first time, he is the form player at the moment. Alex is probably more consistently playing high level tennis but at the moment its at least 50-50. My money is on Nick, who has more to prove after many have written him off.
