I share your reflections . If we could bring in a Randolph level keeper, central defenders and a no6 I think we'd be one of the best teams in the league.
For me yesterday was so very enjoyable until they scored, some of the best football Ive seen us play. We were brilliant as a team for 60 mins but then tired and were poor as a team. I don't think it's just individual errors, as a team we lost our way against a Hearts team who until they scored didn't have the crowd with them.
Suspect we'll learn to have better ball retention and like you mentioned a few prudent signings will really help us.
