Rui does talk nonsense at times. To say that one tactic is more skilful than another is simply bollox. What can be said is that those who kept several transfers in hand this season were lucky. This was because this season there was (i) a big opportunity to use those spare transfers sensibly
AND (ii) the players which were the obvious use of those spare transfers delivered big time. In some seasons either the opportunities to use those spare transfers don't exist to the same degree that they did this year, or that those opportunities don't turn out to be that profitable. Next year it could well turn out to be a waste of transfers to keep several spare up to near the end of the season.
Mark played particularly well as at the death he was in with a chance with a multi club team
AND one crammed with Man City players. In other words although he was not a large multi he used a tactical approach open to all those with several teams.
A large multi displaying as much skill as Mark should have been in a position to have trumped his pairing.
P.S. I've only used the word skill to be consistent with Rui's wording. Personally I don't think that there is ever much skill associated with playing fantasy football. If anyone wants to use a word to contrast with luck as the winning element, "judgement" is a more appropriate word in my opinion.
