Fair point - We might try crossing when we are desperate at the end of a game and then realise we don't have anyone who can head a ball. Although not the tallest Connolly can at least head a ball, but he isn't going to get on the end of crosses, playing at left back.
Agreed there is no point going down a rabbit hole with the stats. Goals and assists from our forwards tell you quite quickly we haven't found a combination that gels. Wellbeck has been the best of a bad bunch and is also possibly the simplest one to change out. It isn't always the obvious...
