Watson is pretty useless with the ball. Not to mention the fact that he's barely played enough domestic cricket yet he almost walks into the team where as Noffke works his ass off weekly to be one of the best all-rounders in our domestic competition and not even get a second look.
Watson bowling came along real nicely during the India tour and he continued it in Aus. He is able to keep it tight and has got a bit of reverse. It is enough for a 5th bowling option.
I wouldn't rate Noffke batting anywhere near Watson, he is more around Lee's level. His bowling is clearly better but with Lee and Johnson they have him covered. If Noffke wants to be considered a genuine all rounder he needs to get himself promoted to 5 or 6.
