Sorry but I find that to be completely wrong!
His kicking off the deck is much better than his kicking out of hands. If you have the misfortune to sit amongst idiotic duffers who **** themselves every backpass then try really hard to ignore them and watch what actually happens. 9 times out of 10 it is a pinpoint ball on to Lambert's head. Yes, if a backpass puts him under pressure he might whack it out but that's probably sensible.
His kicking is better than that of most goalies I see play against us and it's certainly better than Bart's which is barely professional standard at times.
If people have criticisms of Davis then fair enough, but this refrain you often hear about his kicking being poor is just plain ill-informed. He may have made one or two mistakes in the past but for the last season and a half it has been very good.
