The defensive record improved when playing out, so no, I don't buy that it leads to unnecessary goals conceded anymore than lumping it forward and handing back posession. I dont think you need to look much further past the lack of available wingers and strikers for the reason there was a lack of outball at times last season and we struggled to create.
I do think if you launch it to midget midfielders playing in the absence of pace and a decent/fit no9 then you're ultimately going to invite more defensive pressure than playing through the 3rds and keeping the ball.
