Nice to read all of the above comments.
I really don't know whether Adam is the next big thing...I was thinking someone younger than him like a Jason Day or Nick Flanagan? I saw him at the Australian PGA on TV and his putting was TERRIBLE! I seriously couldn't watch..so I don't know how he could go about it but he needs to fix it up quick - it was painful to watch! His ball striking was magnificent as always though and hopefully the disappointment of 2007 can carry him on to make up for it in 2008. Not sure whether he can win a major next year but hopefully sooner rather than later.
Justin has been solid for a few years now and this year has come right through - he has a fantastic record in majors and now ranked higher than Adam so I think he could definitely go close to winning one next year!
