Birmingham ended the opening half having had two thirds of the possession, and yet, their xG [expected goals] figure of 0.33 was dwarfed by the 1.61 managed by the hosts.
Davies' men badly needed a spark in the final third but, despite the best efforts of Gray, they found it difficult to trouble Okonkwo.
Having had huge defensive concerns of their own earlier on in the season, Wrexham showed a resilience and stubbornness that will have delighted boss Phil Parkinson.
They also carried a real threat - particularly through O'Brien and Kabore - on the transition.
But with the grim conditions in their favour, the Blues improved in the second half and had Roberts to thank for them leaving north Wales with a point.
Despite the contrasting styles, both sides showed they are, and will likely continue to be able to compete in the Championship this season, despite being in the third tier just a few months ago.
The duo are highly ambitious, and at a rare time where the Championship does not have a runaway side seemingly destined for the Premier League, the division appears to be wide open.
Granted, patience will certainly be needed among the supporters of both clubs, but they can be buoyed by the fact their sides are certainly holding their own at this level.
