If the West Indies can learn to follow the wickets-in-hand strategy, surely England can, without nuking their team.
Broad and Anderson were over-bowled in the latter stages in both matches, but on paper they're the two quicks who it would make sense to use. England will obviously reconsider that tactic. So too, Monty could have bowled one or two late overs to offer some variety, but it's no good having a plan b if you don't have a plan a in the first place.
