Was thinking the same today, not sure. His keeping has been greatly improved and he is tidy but he doesn't really have to deal with either express pace or a big turning mystery spinner. But he does a good job with the swing (and late swing/dip) of his seam bowlers and spin of Swann, and that is all we have to jusdge him by, and his batting really is a big plus.
Lets just give him some more time.
