He has a mcgrath like accuracy and the ability to get some very late swing
I'd take him over bird or hazelwood. As good as those two bowlers are, Chad is even better

keep in mind he has managed a bowling average of 23 in adelaide. Best bowling average in the toughest conditions

Sadly he is 29 so even if we select him he doesn't have much time left. Much like o'keefe we may have missed another once in a generation quality player
