Watching Slade turn in a match winning performance for England, one thought of Jesse Kriel. Slade made 3 clean breaks and scored 2 opportunistic tries. In 40 tests Kriel hasn't turned in one performance as convincing.
Why? I'm sure Slade isn't as strong or as fast as the physical Kriel. The difference is in the software. He is a smart player, alert to the opportunities and with some real vision. Kriel by contrast appears stuck on his post.....rugby by the numbers.
England now has one of the smarter backlines in the game. Farrell is a warrior and an emotional player. May is a speedster. Tuilagi is a power house. But Youngs, Slade, Nowell and Daily seem like very cerebral players. Which is not to say that Ioane would win a contest with Nowell....but sometimes brains matter.
By contrast with Kriel, Allende in the centre we have a backline with little intuition.
