On the rare occasion Smith does bowl these days, he doesn't threaten anyone. He bowls a lot of long-hops and full tosses. Perhaps his bowling has fallen away since he began to focus on his batting, but in my opinion he doesn't provide anything with the ball these days.
(Apologies in advance for this,
@Keatoboy!) I also don't see why anyone rates Head's bowling. I can't see him being at all successful as a spinner in Test cricket. Just doesn't look threatening at all every time I've seen him bowl, and his stats aren't great either.
I don't think a couple of batsmen who bowl a bit is good enough. What's the point of having them get through a few overs an innings without looking like taking a wicket. Personally, I'd pick someone in the top 6 who is a competent bowler.
As for the wickie, I'm really hoping Whiteman can have a run of good form. At the moment though, Wade doesn't look up for it. In India at least I'd bring back Nevill.
