I'm not convinced it was Root's fault that Archer got injured.
He probably did over bowl him a little, but then Archer often seems to need 2 or 3 overs to get up to full speed.
I'd always pick Wood ahead of him in tests.
There's no certainty that Root contributed to Archer's injury of course, but he certainly over-bowled him. He had had very little first-class experience before playing for England and needed to be managed properly, but Root treated him like he had a new toy. I love Wood, but he really only has his speed as a threat. Archer can match him for speed, but has guile as well. He could be England's first-choice for 10 years, if handled appropriately.
