To take it back to the topic, being Joffa,....Joffa doesnt stack up numbers with flops, he genuinely is very hard working defender and will make a LOT of solid, safe, effective tackles, one on one or in numbers, head on. Pous point is sound regarding Joffa for most of the game, defence is his strength and he'll tally up decent numbers, even per minute.
But when he is tired and the opposition gets the defensive line moving laterally, look to oppositions hitting 1m inside him. Often it wont even hit Pou's stat sheet as a missed tackle because he wont get a hand on them.
