Williamson needs to play less limited-overs cricket

Williamson is good enough to make the Twenty20, one-day and test teams, no questions asked, but I ask: is lining Williamson up in every game giving New Zealand the best chance to be a strong test nation – the format that every cricketing country is judged on. During the early part of the test series against South Africa, Williamson was out of sorts and my belief is that it was a hangover from playing so much limited-overs cricket in the leadup to such an important series against the world's No2 test playing nation. Williamson's key problem was he was pushing at too many balls outside off stump. He was defending balls he had no need to play at.
