Attacking set pieces are rarely, if ever, the difference between a mediocre and a good team.
That's not what I'm saying. I'm saying the regularity of goals we concede from set pieces could be the difference between us finishing in a mediocre 8th or a respectable 4th. Plus the amount of goals we score from set plays (or not as the case may be) could also be a significant factor.
People rave about Spurs and their great pressing play and new brand of football but 40% of their goals have come from set plays this season, according to the official Premier League website. Over half of Palace's goals have come from set plays as well. Both teams above us in the league and both teams would kill for the attacking talent we have.
We've scored the most amount of goals in the league from open play which is great, but imagine if we put time, effort and a bit of ingenuity into our set plays as well? At both ends. We'd be higher up the league than we are now with less goals conceded that's for certain.
