I'm sure those that are always critical will point to that article as to why this is a bad signing.
however, to me, it looks like the smallest of margins, and the All Blacks have the option of being ruthless in that way.
I feel that the English club game is filled with players whose decision making is not instinctive, or is slow/poor.
That article suggests that Fekitoa's decision making was seen as being fractionally too slow for the very very top of the game, but not a weakness at club level - even with the speed of S15 rugby.
I feel like it won't be a weak link for him at club level or maybe even european level, and his physical attributes will mean that he'll have the pace and power to handle what will be thrown at him on a weekly basis.
If his desire is there, and hopefully having a friend at 10 will help, then this could be a fantastic signing
