I think that's because we now have a head coach who fully understands how to be defensively efficient when out of possession. we're certainly much more controlled and far less gung ho than under Lowe and Schumacher for me.
Foster to me is a real thinker of the game and a head coach. Be interesting who he keeps bringing in to be able to deliver the style of football that he wants. I've certainly seen glimpses of the style of play I think he's trying get the players playing - and it looks very encouraging.
And worth noting he's still unbeaten as an Argyle manager winning both our home games 3-1 and both away games 1-1 (Something Schumacher hasn't achieved at Stoke)
