Effective is the wrong word but some data can definitely be used as a better predictor for future performance than simply goals scored. If a team is consistently creating big chances but aren't scoring over a 5 game spell while a team is scoring but they are all long distance goals, penalties and 'lucky' goals, the first team will probably do better over a 30 game spell than the second.
That is not the case here though, Boro are creating a load of poor quality chances and are also not scoring. I don't think they are all that good.
I'd agree with all of that.
It was clear that, just because Sheff Wed scored four goals against Plymouth, and probably had decent stats, it didn't mean they'd keep scoring. I'd not even look at stats until we've played fifteen games and things start to balance out ...
... I've no idea of the stats under Mowbray but, quite often, we'd be heading for a low or zero score when Amad would score a 'wonder goal' and the stats would go up in the air like dominoes in a Friday night workey
